Routine for 12 Week Old Baby

Having a baby between two and three months old can feel like time has either flown by or dragged on. It’s becoming harder to remember life before your little one arrived.

Babies have a way of consuming all your available time. You might find yourself spending hours just gazing at their little face.

By this age, most babies become very social, giving lots of smiles and cooing, which naturally helps you fall in love with them over and over again. Babies are naturally skilled at drawing you into their world and building strong emotional connections.

8-12 Week-Old Baby Patterns

Your days are likely starting to have more predictability. Although no two days are exactly the same, you’ll notice a more consistent routine emerging. Your baby will feed more regularly, sleep less erratically, and you may feel more settled.

While you’re still likely to be tired and your baby isn’t sleeping through the night yet, those intense early days are behind you.

Feeding

If you’re unsure about your breast milk supply, consult with your child health nurse and have your baby regularly weighed. Avoid introducing formula unless advised. Many mothers interpret their baby’s fussiness as hunger, but it could be due to other factors like overtiredness.

Expect your baby to cluster feed in the afternoons. Try to run errands earlier in the day so you can be home when your baby needs more attention.

Three Tips for 8-12 Week-Old Feeding:

1. Longer night stretches: Expect a longer break between feeds overnight, sometimes up to six hours. Make the most of this and go to bed early.
2. Increase bottle feeding volume: If your baby is bottle-feeding and seems unsatisfied or unsettled, you might need to increase the amount of milk. Signs include draining the bottle quickly and being hungry again soon after.
3. Snack feeding: Your baby might want to feed for reasons beyond hunger, such as tiredness, boredom, or needing comfort. Breastfeeding at this age is more than just nutrition.

Sleeping

Your baby might not be a quiet sleeper, often making noises that sound like they’re waking up or in pain, but then they go back to sleep. Avoid hovering too much and give them space to settle themselves and play on their own when they wake up.

Three Tips for 8-12 Week-Old Sleeping:

1. Transition to a cot: If your baby is waking themselves up in the bassinet, it might be time to move them to a cot as they prepare for rolling.
2. Normalize household noises: Avoid tiptoeing around the house. Exposing your baby to normal domestic sounds can help them become less sensitive to noise.
3. Soothe with movement: Your baby may fall asleep while driving or in their pram. Rocking and movement are especially soothing for tired babies who resist settling in their cot.

Behavior

By now, your baby has visibly grown. They might be wriggling out of their wrap, needing more floor time each day with toys and bright objects. Watch as they “talk” to familiar toys and show excitement with noisy toys and rattles.

Three Tips for 8-12 Week-Old Behaviour:

1. Stay close: Your baby will want to be close to you. Even if you can’t hold them, make sure they can see you and hear your voice if they’re unhappy.
2. Head bobbing: Be careful of your nose and cheeks when your baby is head bobbing. Their head control is still developing, and they might need frequent rests.
3. Interactions with siblings: Pay attention to how your baby reacts when older siblings are around. You’ll hear different, excited noises as they communicate.

What’s Important 8-12 Weeks After Birth:

– Monitor your emotions: Speak with your GP if you’re worried about your emotions. Symptoms of sleep deprivation can resemble postnatal depression, and it’s hard to be objective about ourselves. Low thyroid function is common in new mothers, so ask for a thyroid function test if you’re concerned.
– Involve your partner: Encourage your partner to be as involved as possible in the baby’s care. It’s important they feel they are contributing and not just a bystander.
