baby cant sleep...

Ok moms, so my 11 month old daughter is having trouble falling asleep... It takes like 2-3 bottles for her to fall to sleep. Nd no im not trying to force her to sleep, her eyes have been so droopy nd red.. Nd she closes her eyes than just wakes right up. She cries cuz she is so tired and cant sleep, i feel so bad... Ill even bath her just so she can take a nap during the day but sometimes thats not even good enough...
