Since Monday DD2 (23 and a half months) will not go to sleep without screaming non stop solidly for an hour or more, desperately wanting to be cuddled to sleep - something she has not ever wanted before. I can't remember DD1 having tantrums on this scale and we're stuck between not wanting to give in (which I did for first two evenings) and create a habit, or whether perhaps there is actually something wrong ?! (teething jumps out at me) - any thoughts anyone? This is making for very unpleasant evenings!
