Introducing a new baby to your toddler: avoiding jealousy and building connection
Recognising the signs of sibling jealousy and helping your toddler feel seen, safe, and secure
When you bring home a new baby, your heart may feel full, but for your toddler, it might feel like their world has just been turned upside down. And that is completely normal. Welcoming a new sibling is a big adjustment, especially for little ones who are used to having Mum and Dad all to themselves.
If you are navigating this transition and wondering whether your toddler’s behaviour is a sign of sibling jealousy, or how to support both children without losing your own sleep in the process, you are in the right place.
Signs your toddler might be jealous of the new baby
Every child reacts differently, but here are some common signs that your toddler might be feeling displaced:
- Regression in toilet training, sleep, or independent skills
- Acting out with tantrums, clinginess, or refusal to follow directions
- Demanding your attention when you are busy with the baby
- Mimicking the baby, wanting to be carried, fed, or rocked like a newborn
- Verbalising dislike (for example, “Send the baby back” or “I don’t like the baby”)
These behaviours are rarely malicious. They are your toddler’s way of saying, “I need help coping.”
How to introduce a new baby to the family (in a toddler-friendly way)
You do not have to wait until the baby is born to start laying the groundwork. Here are some proactive ways to ease the transition:
- Talk about the baby early, but in toddler terms: Use simple, positive language. For example, “The baby will be so lucky to have a big brother like you.” Show them pictures of babies, or read picture books about becoming a sibling.
- Create a ‘big sibling’ role: Give your toddler small, age-appropriate jobs such as handing you a nappy or singing a lullaby. Feeling involved can transform anxiety into pride.
- Set aside one-on-one time: Even ten minutes of focused play each day, with no baby in sight, can go a long way in filling your toddler’s attention cup.
- Talk about emotions openly: Name what they might be feeling. “It’s hard to share mummy sometimes, isn’t it?” Validating their emotions helps reduce the need to act them out.
- Avoid blaming the baby: If you are busy, say, “I’ll help you in two minutes” instead of “I can’t, I’m feeding the baby.” This helps avoid fuelling resentment.
And what about sleep?
Sibling jealousy often peaks during bedtime, especially if your toddler was once the centre of the evening routine. You might see sudden bedtime resistance, extra wake-ups, or anxiety around being left alone.
In these cases, consistency and reassurance are key. Here’s what we recommend:
- Keep your toddler’s bedtime routine predictable and comforting
- Offer praise for their “big kid” sleep habits
- If needed, reintroduce short periods of parental presence at bedtime, gradually fading out again
- Consider a reward chart or “sleep fairy” for motivation
Remember: “Everything your child knows about sleep is because you have lovingly taught them.” This applies to emotional regulation too. They are learning from you every day.
