Help - 15 Month old sleeping issues

My little girl is almost 15 months old, and although she slept through the night almost from birth when she hit 5 1/2 months she started waking and now at nearly 15 months she is still waking and wakes anywhere from twice a night to 5 times a night.

We have changed formulae to a lactose free one, from about 9 motnhs as she used to wake with alot of wind and seem to be in pain, changign to this formulae stopped the pain but not the waking. She has a bottle before bed, and usually another full bottle around 11pm, but then will wake almost 2-3 hour from there, she wont drink much water at night, but will drink a bottle.

She is not a big eater and seems to pick at her food, she is a good weight, but want her to sleep through. I can't do the cry it out method as she shares a room with her 10 year odl sister, she slept inour room in her cot until 13 months so it doesn't matter where she sleeps she still wakes.

Can anyone suggest anything?

Yeah I do think its probably habit, but how do I break the habit, she is at day care all day, The only reason she has a bottle at 11pm is usually because she wakes and she doesn't drink a full bottle before bed sometiems its only about 40ml. Around the 7 month mark we started giving her a bottle in bed as advised by plunket because if we gave it to her before she went to bed she would only drink 30-40mls, when we started giving it to her in bed she drank the lot, but would still wake. Plunket said if she was waking at 11, offer her a bottle in case she is hungry and she usually drinks the whole lot being 220ml. I stopped giving her a bottle in bed resently because I thought perhaps she was using teh bottle as a sleep aid, which i didn;t want to encourage, and although she can get to sleep without any problem, i stil don't klnow if she is waking because she is hungy or habit, but if its habit how do I change the habit, without letting her cry for hours on end, we have tried rubbing her back, giving her a cuddle and sometimes that works ands sometimes it doesn;t. my doctor has told us its teething but I rally don't think teething can be causign this every night !

There's a few books out there that i've seen that are sleep training without cry it out. Maybe the No Cry Sleep solution or something. Try the library, browse a couple, see which one fits with you and then be super consistent. You may need to move older daughter in with you for a week or so till it's sorted as you'll be in and out by the sound of it. I agree more likely to be habit at this age. At least she should be sleeping from the 11am till 7am cos she has a nice full tummy then.

Jack has never been a great sleeper. I disagree regarding the teething as I am sure that is what caused some of our problems with waking at night, he averaged a new tooth a month from 5mths to about 2yrs. Once the last tooth cut (oh and I discovered ibuprofen) things changed.

I 2nd the use of the "No cry sleep solution", also the ""No cry sleep solution for toddlers" and "Sleeping like a baby" by Pinky McKay. We used bits and pieces from all 3 books to help us and we got Jack's sleeping sorted without any of us crying!
