Isaac's started waking at 5am He was happily sleeping 7-7 for months now, and he has been teething lately but has a lot recently and its not affected his waking before. Could it be to do with his Dad's work shift patterns changing? Only I can't think of anything else that's changed. It also means he then has a 3hr mid-morning nap and a power nap around 2-3pm, lasting about 45mins. Why's he changed his waking/sleeping times? Thankyou in advance for any suggestions
