My dd is nearly 7 months, and is breast fed.
She completely refuses a bottle, i have tried loads of different ones, so my husband cant help with feeds. She wont have a dummy either.
In the day she only naps on me when feeding, or in the car.
At night she pretty much feeds every hour throughout the night, and isn't in a routine at all as she doesn't sleep long enough to go to bed at a normal time, so I just keep her downstairs with me and cuddle her all night till I go to bed 
I love all the cuddles, but I have other small children, and I'm knackered! Because she wont take a bottle, I cant even go out for a few hours ever
I have found a sleep consultant on the internet, but it seems very expensive! This is for 4 weeks of support though, and is done over facetime. It's all gentle techniques so no crying it out or anything.
Has anyone done similar? I'm not trying to get her to sleep through, just go longer than 45 minutes, and maybe get my evenings back!
