Re: 8 month's old and won't sleep for more than 2 hours at a time
Hiya, I have an 8 month old daughter so I slightly understand what you are going through!
The key is routine.
Does your baby have solids yet? if so, maybe think about dropping a day time bottle, we done this and replaced it with a fruit snack (dropped 4pm bottle) dinner at 5pm bath at 7pm bottle at 7.30pm then bed and she sleeps through until 8am.
Does your little one have a soother? Maybe they want comfort in the night?
Another thing to consider is if you baby is still in your room, they maybe getting disturbed by you in the night?
