My 2 year old daughter was a bit clingy before...although I think it was more boredom than jealousy as all my dck's were boys and nobody really clicked with her in terms of wanting to do the same things. I recently started a little girl who just turned three and I barely even see my daughter now LOL She is soooo happy because she and the other little girl play dolls all day long...they are like little soul mates...they never fight...always agree on what to play and how and are stuck to each other like glue all day This was so lucky for me, but also took making some hard decisions which fortunately paid off I hope you will find a child who clicks like that with your child and then hopefully he will be less clingy.
