I used to get so sick of people saying "oh, is DD#1 jealous?" when DD#2 was born..........how could a 29 month old be jealous? I just didnt understand that question. She was so accepting of her new sister......if you show both children equal amounts of attention, i dont see how one can be jealous of the other.
First thing DD#2 says when i get her out of the cot in the morning.....'mimmy, mimmy'- nickname for DD#1.....and then its a big sloppy kiss and a 'morning' hug....

I think the jealousy comes when they're in there teens.....IMO......thats when me and my sisters hit sky high !!!!LOL.
