Ds just turned 8 months a week ago. He use to sleep very well, at least with me through the whole night. All the sudden he is waking at 330am or sometimes around 5 and wanting to completely get up and play. Does anyone have a clue as to what the hell is going on and if this will stop? I live with my sister and her 3 month old waked us on and off as it is.I am soooo tired lately and am really hoping this is a SHORT phase. Is he just needeing less sleep at night as during the day? I have even tried putting him to bed a little bit later and nothing is helping.
