My little girl is a little over 7 month. She used to wake up only once or twice at night. It would usually be at around 4-6 AM (going to bed at 10). Well, for the past 4 days she's been waking up every hour! Some times it would take me just rubbing her back for her to fall asleep, other times it doesn't work and I need to breastfeed her, which is most times. She already has 2 bottom teeth for a month, and top gums don't look like there are about to pop teeth... What could that be? She's my usual happy baby during the day...
