Its sooo hard cos it seems like you are the only one going thru this and everyone else seems to have a little one who has slept thru since day 1, but you are not alone. I would just say perhaps give the solids a little longer as maybe once she starts having more in each meal & More meals then maybe that may help. Its so hard, and people would say to me maybe its her teeth, maybe shes to hot/cold, maybe she needs to sleep more/less in the day, maybe its this, maybe its that - who knows - I never did thats for sure!! We have now had about 4 weeks with lo sleeping thru, hopefully something will just click for you soon and things will improve - ours seemed to be just habit and took a few nights to break it, but who knows with babies - could all change again tonight!!!
