I'm sleep deprived. My nipples are sore. My 9 month old wants to nurse the whole night and cuddle. He is been like this for a week. I am hardly getting any sleep

He teeth was cutting through and is pretty much out. He is okay during the day. Has 2 naps, eats if he likes the food. Plays and is quite social. It's just at night he just want to be on boob. He doesn't take bottle. Doesn't sleep in his cot anymore. One sleeping stretch at night is 1.5 hour if I'm lucky.

At day time I have cut down feeds. He feeds when he finally wakes up, after breakfast when he naps and after lunch and before bed

He is my first! I don't know what to do. I dont know what I am doing wrong. He would wake up once or max twice at night before. Now I loose count.
