Our little miss recently turned 1, and up until 3 days ago we had her back to sleeping very well at night and patchy during the days. However recently she has woken up screaming hysterically when ever she does wake up. We use Hylands Teething Tablets, Nurofen/ Panadol (when needed). She is warm as she is normally in a warm onesie (since she wont keep blankets on), and we have checked her temp and it has been normal. She is not constipated, and she eats a fairly decent meal before her bath, and last night feed. (she is exclusively Breast fed & solids, we started introducing some full cream cows milk about 3 weeks ago). Any ideas on why she would wake up screaming so much? (sometimes can be twice in a night). Why is my 1 year old waking up screaming?
