My 16-month-old son welcomed his new baby sister home a month ago and seemed to love her instantly. Now he's very upset. He won't eat like he used to and throws tantrums. I tried to introduce them properly by letting him touch her and show her all his toys. I try to pay equal attention to both except for breastfeeding the new baby and not my son. He recently stopped being breastfed. Is there anything I can do to help him?
Look at your son's jealousy from his perspective. Suddenly he has to share the most precious thing in his life: you. No wonder he's upset! The emotional regression he's showing is his way of letting you know that he still needs you. The best way to help him through this is to pay lots of attention to him when you're together and to spend extra time with him when his baby sister's asleep. Don't worry about whether you're paying "equal attention". That's impossible. If you focus on his needs at the moment, he'll soon accept his baby sister.
