DD2 is 14 months old and whenever DD1 is getting attention, DD2 wants to muscle in. If I am being affectionate towards DD1, DD2 comes shuffling over (bum-shuffler here )and makes disgruntled noises until I pick her up too.
That's fine, but if I try to sit a child on each knee, or if DD1 remains anywhere near, DD2 shoves and hits DD1 quite forcefully. She's a large baby and DD1 is a petite 4 year old. It's not very nice for DD1. I explain to her that the baby doesn't know yet how to share.
How normal is it for the younger sibling to act out jealousy towards their elder sibling. Will it stop?
