My 3 month old has been sleeping and napping a lot more these past two days. He doesnt have a fever or any sick symptoms. He did go from eating 4 oz to needing 5 oz every feeding to get him full. He also is chewing on his hands so maybe teething but he sleeps really well at night. From 930 pm till 715 am and only gets up once at night to feed. But he has slept A LOT thru the day lately. Any ideas or am I over thinking it?
