oh man, that is my daughter! in some ways she is so independent, if i want to help her with something, its "NO I CAN DO IT MYSELF" but if i want her to do something, she cant, shes a baby, shes too little, etc... needless to say, toilet training is going nowhere. shell do it "when she gets bigger".. she has even developed this lispy kind of baby talk thing. i dont know what advice to give you, i think she is just responding to not being the baby anymore and is jealous of all the little one's attention. i try not to make a thing out of it, because once she digs her heels in, thats it. and i dont want to make it into a battle, so i just tell her about the things that she gets to do or will get to do because she is bigger, and i try to let it go. but shes the middle, so she really does get the short end a lot. its been a bit better lately since ive been making a concerted effort to give her extra attention, just about her, more one on one with her. just wanted you to know youre not alone... and i will be coming back to your post for advice :)
