My daughter who turned 4 months this week was poorly with a cold/sicky type thing last week, come Monday she was sleeping through again and seemed fine in herself. However the last couple of days she has slept constantly- today 3 hours on me as so clingy and will not take much much milk, 3oz max - I am offering regularly because of this. She usually takes between 6-7oz. Even after sleeping through the night she only took 3oz and refused anymore after that. She doesn't appear to have thrush as i can't see anything in her mouth and when she is awake we are getting lots of smiles - albeit clingy and cries if we leave the room. Nappies all ok. She seems to just lobe blowing bubbles instead of drinking?! Any advice?
