Our LO is 13.5 months old. Last night was very rough. She woke up every 5-10 minutes since 11am until 1am and then from 4:30 until 6am. We know how she is when she is teething so that is ruled out (she has 7 teeth). The only other time she has done this is when she is a day or two away from showing symptoms of a virus.
Does anyone have a little one that does this? This is not something her bigger sister did...she would just sleep more soundly when coming down with something.
