Please help, My 14 week old daughter wakes at 6am for feed, won't go back to sleep but happy to lay in cot for a little while (mind you that's depending on what day it is), has a little play on floor and kicks with no nappy till 10am feed. Struggles to stay awake to finish the bottle, so I put her to bed.... Maximum time of an hour she's awake again, not happy to be in cot or held or play on floor. Will have another light nap of 1/2 hr before 2pm feed. Has up time of 1 to 1 &1/2 hrs then sleep for only 1/2 hr to 45mins max. She's so tired every day, Don't know what I can do!! Please help!? She's showing some signs of teething, could this be why???
