My lo will wake every couple of hours but I've got quite a fast letdown so is done feeding in 10mins and falls straight back to sleep so I get about 6 hours sleep a night. I left him with my oh to go to the cinema and he gave him a bottle of formula, when I got back lo fell asleep for 5 1/2 hours! But not sure if that's because he hardly slept and was very fussy when I wasn't there, he missed his mummy!
I'm so fed up of my smug twin sister bragging about her lo who is a week younger than mine sleeping through!!
Don't give up yet tho hun I'm sure it will get better eventually! Have you tried expressing a feed first thing in the morning when your supply is at its best, and giving it to him at night? Xx
