Hi there! Could you post your current routine, it may be that she just needs a tweak... Is she waking up at 10 and going to sleep at 10? That is a very late day and may be affecting her somewhat. How are her naps? Did your DR recommend starting solids? 17 weeks is awfully young for solids and they may be a bit much for her. Typically solids don't start until about 6 months, and they don't *really* help with STTN until 8-9 months for most LO's.
