Since baby Iggy came home from the hospital Anna has for the most part ignored him. At the time I was understanding since she was the baby princess and youngest and suddenly she wasn't.
Every once in awhile she grabs his arms and feet and plays with him a little but it's about once every 4 days or so.
I never pushed her to play with him because he was so little and fragile and she was rough without meaning to be the few times she played with him but I was getting kind of jealous of seeing pictures of siblings their age already playing together so I started encouraging her a little more.
Today she wandered over to him in his jumper and ducked down and whispered hi to him and he smiled and cooed back at her. Of course when she noticed me she went back to ignoring him :)
