When my husband and I decided to try for another baby part of our motivation was to give our son a sibling. He had (and has) a great temperament and loves “babies” (which is any child regardless of his or her age). We felt like our family was ready for another baby too. Even though I knew that our son would be a great big brother, I did have concerns about how they would get along. On his side of things, he has always had genuine love and concern for her well being from the moment he first held her (two hours after she was born). She did not seem to have any opinion either way about her big brother.
Now that our daughter and our son’s baby sister is five months old and very interactive, their relationship has really evolved. They seem to really enjoy being together. On the rare occasion that our son sleeps with us, our baby daughter will snuggle up to her big brother putting her hand on his arm or her feet between his knees and he will but his arm under her head. Our son also enjoys sharing stories with his baby sister. I have miraculously caught these precious story time moments on video. He will “read” his favorite books to her from memory while helping her turn the pages and she will listen intently seemingly loving the sound of her brother’s voice.
Recently we have discovered that our son has the special and unique talent of making his baby sister laugh uncontrollably. I cannot exactly pinpoint what exactly he is doing that is making her laugh so much. Perhaps it is his interaction with her with his crazy facial expressions that gets her laughs going. It also could be his exaggerated movement e.g. jumping from the arm of the sofa onto the cushions (something I do not like him to do for fear of him falling and injuring himself); she thinks it is hilarious. He has also taken to teaching her how to do things like play the drums or put on shoes. It is very clear that she adores her big brother and that he loves her right back!
