Jealous

I am babysitting the neighbor girl everyday while her mom teaches school. My neighbor was in desperate need, so I sat Colby down and asked how he felt about it, since we had made such a big deal about it being just him and I this year. He was really excited and said that we should for sure watch her. Then he asked me EVERY day when we would start watching Kyleigh. Well, on day 2 I was tickling her and playing with her while he played with his trucks nearby. After about 2 minutes of me playing with Kyleigh, he gets up on the chair and folds his arms and says, "Mom. I don't want you to watch Kyleigh anymore. I think it should just be you and me." I told him it was too late, Donna was already counting on us. Now he asks me every day when we will be done watching her. She has a program that she can go into November 14th and my bday is November 19th, so I have told him we are watching until my birthday. He tells me everytime I am snuggling him that he wishes it was my birthday already. The baby doesn't do so well having another baby around. I think it's GREAT for him.
