Hey darl, I went through a phase like this with dd as well. (I didnt see you say whether you bf) but i'll just let you know our story and how we changed it around. Of course we still have off nights because of teething, they do tend to teethe for a while before actually cutting teeth. Panadol and teething gels have been our saviour, but anyway. here goes..

I make sure dd has 4 bottles a day regardless of whether she drinks it all, cause I noticed that was contributing to not sleeping much during the night cause she hadn't eaten enough druing the day. So I decided to do a nightly routine which now consists of:

5.30pm Nice warm bath bit of a splash around, then dressed and given a massage with either moisturiser or baby oil

6.00pm Solid feed. (vegies and meat) with some water

6.30pm Bottle feed, nappy change and then into her bedroom with dim lights to read her a book before bed.

Then once I put her to bed, just put her dummy in and her mobile on and she will sleep till 6.30/7am

I mean of course my routine isn't going to work for everyone, cause all babies are different. But just thought i'd give you an idea. HOpe it all works out
