Abbie goes through spells like that - Sat night in fact
Mum and dad were babysitting, and she went down dead easily as usual, but got up about 11.30 and up till about 1.45 am. Gave her medinol and still nothing. We had to ride it out until she settled. She wasn't hungry, but has a cold again
so could be your wee one is unwell or in pain too. Think Abbie is also teething again, wee Katie was in agony this morning and that is not like her at all. They both get a bad cold when cutting teeth so maybe that is the problem with you too.
Hope it gets better soon. It aint fun being up all night with them crying. Thankfully for us it is like that one or two nights then back to normal again.
