Not all toddlers will be jealous of a new sibling, but it’s entirely normal for them to feel some jealousy toward their new baby brother or sister. If you’re experiencing this with your child, try not to worry too much. Keep the lines of communication open, be patient, sympathetic, and carve out some alone time with the older sibling. This is often just a phase and something that you’ll be able to work through together as a family.
