OP in the kindest way possible I think you need to lower your expectations.
get rid of every baby book/website you look on and just trust your own instincts. Just trust them
you have a 10 week old. Sorry to say but some babies don’t sleep through the night until they’re 2/3. I have a 10 month old and it’s 50/50. sometimes he does sometimes he doesn’t, yes I’m tired some days but I chose to have a baby and this is what comes with it
by now means am I saying you have to suck it up and can’t complain - I’m saying you need help and support. Please don’t sleep train, some people will try and justify it to you buts neglect and abuse.
your baby is still a newborn. Their needs do not stop just because it’s night time. There’s more to looking after a baby than feeding and changing them, sometimes they want some comfort, they may be scared, too cold, too hot, uncomfortable, wind. There’s literally so many reasons why your baby is waking up but they are all equally deserving of a response. Despite what we are lead to believe, most babies do not sleep through. They aren’t meant to! Babies are meant to wake up often to keep themselves alive. Not one single human being sleeps through the night, anybody with a Fitbit can tell you that. We toss and turn, we move around and move the duvet. Sometimes we need a wee. Sometimes we just can’t sleep , so why would a baby be any different?
in the nicest way possible, you need to accept you probably aren’t going to get any decent sleep for a very very long time and if you do then it’s a bonus. But please don’t expect your baby to sleep through.
