If you had a 7 year old, you would be me!!! My daughter is 6 weeks old, and my now 16 month old has decided that he loves her...until I am feeding her!! He has gotten better, at first he wanted me to hold him everytime I had the baby, and even tried to push her off of my lap a time or two. Also, he cried when we put him to bed for the first time ever, but I think that had a lot to do with me being away from home for 2 days..I put him to bed the night before, but was in the hospital when he woke up to a babysitter. His sisters were spending the night with my sister, but I wanted him at home in his own setting, thinking that he might do better with that. I just tried to be empathetic and was worried that by getting him up I would ruin him for life, but that did not happen, he has adjusted perfectly now. Be sure that you never leave them in a room alone, my son found a pencil when I was helping someone in the restroom, and I came out to him poking his sister on the head. Luckily it was a very dull colored pencil, but it did teach me a lesson. She was in the swing, but that is apparently not good enough...and dont even ask where he found a pencil!?! I always let him sit with me when I am holding the baby, telling him that mommy always has room for both of them, but that when she is getting a bottle, it is her time alone, and then I will hold him alone when I am done. It is a little hard for him to understand completely, but even if he pitches a fit on the floor, that is the rule. Honestly, it was not as bad as I though, and for sure has improved with time!! He seems so big now:) What has helped, believe it or not, is getting out of the house. We go to the mall play place or something like that and he and his sister are so occupied that they are happier when they are home too. It may seem overwhelming to have them both out, but honestly it is not too bad. Actually I have a 5 and 3 year old that I baby sit too, and I take them all out almost every day, and have been for about 3 weeks. If you have any other questions, or just need some one to feel your pain, feel free to let me know!!!! ~A.~
