My Lo is 4.5 months old and a good night sleeper. Goes to bed at 7:30-8pm everynight and dream feeds at 10:30pm everynight. She gets up at 5-6am for a bottle and goes back to bed till 7am. Two nights ago she had an over flowed diaper and needed her nose cleaned out when she woke up at 5:45 to eat. So we got up and started the day. Now this morning she got up again at 5:30 am and refused to go back to sleep. Is this turning into a habit, and if it is how do I stop this?
