my son's 10 months.... for the past 2 weeks he wakes up every 3 hours in the middle of the night to drink 3-4oz. then goes right back to sleep. let me start by saying 3 weeks ago he just started sleeping all night then he got sick was sick for 10 days then 2 more teeth came in. but now he's just waking up to eat. what do I do? he's eating enough throughout the day and were on a good schedule...
