My son turned 4 a few months ago and I love how thoughtful and sweet he is.
We're expecting a baby in July and DS is very excited about his role as big brother. In fact, if someone asks him if he's looking forward to being a big brother, he will answer most indignantly, "I already *AM* a big brother!"
Recently DS brought up of the idea of sharing his room with baby brother. I replied that it's a definite possibility when the baby gets a bit older. DS sleeps on a trundle bed - alternating between sleeping on the top and bottom beds. Yesterday he asked me, "Do you think the top bed or the bottom bed is more comfortable?" I replied, "the top bed" as it has a slightly more expensive mattress. DS replied, "Oh, OK, then I'm going to sleep on the bottom bed and baby brother is going to sleep on the top bed, because I want baby brother to be the most comfortable."
How thoughtful is he!? What a good big brother!
