GOod Morning A., Never feel guilty about not being a get on the floor playing mom. Geee who could when preggers anyway. If its not you don't sweat it. I am not the cookie baking nana, I am the lets play kind or lets read a book Nana.
I think A. once his sister arrives he will be willing to help you with her, get diapers or wipes, etc.. Our daughter in law, Gen, before Zane arrived, would drop off Corbin and he always hugged his mama's tummy and kissed his brother bye bye said Bye Bye Zane. She told him from the start he was getting a baby brother and they were going to be great friends. They are, they still fuse at each other, but the other day COrbin got time out when we were outside. I had him sit on some wooden steps. Zane walked over hugged him and patted his head. Corbin couldn't get up to play so Zane sat with him....lol
Keep reinforcing how much he is going to Love his baby sister and will such a wonderful Big Brother and Mama's big helper.
