My DD is nearly 2 years old. Always been a good sleeper but now all of a sudden won't go to bed. As soon as i say its bed time which is between 6 and 7pm we have full on melt downs. As soon as we enter her room she's screaming, kicking and hitting. We've left her to cry it out the last 3 to 4 nights and after 20 minutes of on off crying she is normally flat out. Tonight though she just is not giving in and us going in to her room to calm her down just makes it worse. She is so tired but like i say not giving in. Is there a point where you just give up and bring them back down? I feel abserloutly awful. But she is to big and heavy now for us to try and rock her.
