10 Week Old Baby Development

Baby development week 10

What can you expect when your baby is ten weeks old? 

Ten weeks into your baby’s development, you’re sure to have a lot of questions about their milestones and what you can expect. Don’t worry, we’ve rounded up the most common questions here…

How should a 10-week-old baby be physically developing?

You will have noticed a couple of growth spurts by this point, with your baby growing two inches and putting on 2-3 pounds since being born. As they’re starting to outgrow their clothes and their Moses basket, it’s time to move up a size. Try keeping the Moses basket inside the cot for a few nights to get your baby used to their new surroundings.

At ten weeks, your baby will be filling out more, and even if her legs and arms are chubbier than you expected, it’s all perfectly normal. Your baby will be starting to realise they can use their arms and hands, finally connecting that they can look and touch things at the same time. That means a lot of grabbing is coming your way.

They should be able to hold their heads up more confidently this week, although not for too long. If they’re having difficulty using their neck muscles, lie in front of them when they’re on their tummy and encourage them to look up at you. 

How should a 10-week-old baby be cognitively developing?

As your baby realises they can use their legs and arms to kick and punch, they’ll start to be more co-ordinated and grab at everything. This is a great time to introduce toys to help hand-eye coordination more at play time. 

Playtime is also something your baby is starting to engage with more; she will love all of the bright colours and new sounds. Allow things to dangle on their pram or in their cot, it will help develop their 3D vision and encourage them to grab at them.

They’re also loving music right now, and will have notably different reactions depending on what type of song you play. Keep singing to them and playing gentle lullabies followed by faster songs to notice their excitement, you may even encourage more smiling!

What jabs should a 10-week-old baby have?

You should have had your immunisation appointment at two months old, but if you’re only just fitting it in or they had to be postponed here’s some advice to keep your baby calm during their vaccinations

During their appointment, they’ll receive their first dose of the 5-in-1 injection against diphtheria, tetanus, whooping cough, polio and Hib (haemophilus influenza type B).

Then, they’ll get their PCV (pneumococcal conjugate vaccine) which fights pneumococcal infections, Rotavirus vaccine (which is a common cause of diarrhoea and sickness) and Meningococcal Group B which protects against things like meningitis and septicaemia. Their meningitis B vaccine can result in a fever, so your nurse may advise you to give your baby infant paracetamol after the vaccine.

They will receive these vaccinations either by injection or for rotavirus orally (a liquid dropped into their mouth). They are given in their upper thigh, one injection for each leg. It might sound traumatic, but should only take a few seconds.

How much should a 10-week-old baby be sleeping?

Usually in the third month of your baby’s life, they’ll be sleeping about 15 hours over 24 hours. That means about ten hours sleep at night and five in the day, spread out over three naps or so. A lot of new parents will worry that their baby isn’t fitting into a certain sleep schedule, but remember, every baby is different and they’re still likely to wake up in the night for feeds at this age.

Your baby’s dummy may now be causing issues, as they could be depending on it to settle themselves to sleep. Try taking it out at bed time, it’ll only fall out in the night, resulting in you having to wake up and put it back in. You may have a few restless nights, but it will be worth it in the long term. To relax your baby before bed, try feeding at about 10pm or before your bedtime to induce a nice cosy just-fed sleep.

If you’re struggling to establishing a sleeping routine, try not to worry – every baby will take their own time to settle into a routine.

How much should a 10-week-old baby be eating?

Growth spurts mean one thing, a lot more food. If you’re following your baby’s lead you may find them eating more, but don’t worry about overeating as they know how much they need – 5-6 feeds over 24 hours is average at this age, but every baby is different.

A good guideline for feeding is 150-200ml per kilo of their weight, but continue to follow their lead if you’re breastfeeding – your baby will know best!  

What if my 10-week-old baby is eating less?

Don’t worry, this is a normal worry for new parents who are used to their baby eating slightly more thanks to the constant growing! After immunisations, your baby’s appetite may decrease. If it does, just know it’s a normal side effect of the vaccines. Their appetite will come back soon enough, but if you’re really worried, take a trip to the doctor for some reassurance, or try switching to formula if your breastfeeding in case they just want a different taste.

10-week-old baby crying: Dealing with colic

Hopefully if your baby has been suffering from colic, it should start to settle in the next few weeks. If you’re still struggling, or your baby seems to be more tearful than normal, here’s some advice to stop the crying

How much should a 10-week-old baby be pooing?

Feeding more means pooing more, but as long as your baby is filling between one and ten nappies a day, or even once every few days if they’re breastfed, they’re usually fine. It’s not necessarily how many times they poo that matters, but more so if it’s passed easily and your baby is not in pain. If you feel like your baby doesn’t seem to be pooing enough, or you’re worried they look uncomfortable while going, your little one might be constipated and need to see a doctor.

Milestones of a 10-week-old baby

  • Tummy Time: With your baby more engaged at playtime, it’s a good time to focus on tummy time. Spend at least a few minutes each day playing with them while they lay on their stomach on a mat. Not only will this encourage them to use their arms to push up and use their necks to look around, it will help your baby develop the muscles she needs to start crawling. Over the next few weeks and months work your way up to 15-30 minutes a day.
  • Weight-bearing: This week, you may find your baby is bearing some weight on their legs. Try it by holding them upright and seeing if they can support themselves for a moment. It’s a big ask, and one you should probably only try when they’re happy and excitable, but testing out these reflexes and muscles is a great start to helping their physical development along.

What problems should parents of a 10-week-old baby be aware of?

  • Flat Head Syndrome: If your baby is spending a lot of time on their back, which they typically prefer to tummy time, they may be at risk of developing Flat Head Syndrome. The continued pressure on one spot of their head will cause a flat spot to appear. During playtime, let your baby spend more time on their tummy, as this will not only reduce the likelihood of this but also encourage their neck muscles to strengthen. You can also wear your baby in a sling to reduce the amount of time they spend on their backs, and increase bonding for the two of you. 
  • Post pregnancy sex: While you obviously are obsessed with your new baby, both you and your partner are bound to have started to miss the intimacy that came before you started this new journey. Your bond will deepen with having brought life into the world together, but it’s normal to feel a bit sad that you no longer only have each other to worry about. It’s also normal for these changes to show in your sex life, which is completely normal and extremely common. Make sure to take some time out and reconnect this week. 
  • Postnatal Depression: Postnatal Depression can occur at any time in the first year of your baby’s life. Are you overwhelmed by guilt or feelings of failure? Do you feel like everything could go wrong and it’s all your fault? You may want to visit your doctor and talk about the possibility of postnatal depression. With one in ten women dealing with it, you’re definitely not alone.
