i just want him to sleep longer 😭😭

Re
My son is 11 weeks old, and he still hasn't slept through the night 😭😭 I know I signed up for the every three or four hour feedings but I thought it would go down by now... I'm just so tired and want to get more sleep during the night but as soon as that three hour mark hits hes awake... sometimes it's even sooner 😭😭 I'm so exhausted throughout the day that as soon as it hits 730 we are both in bed.. I haven't cooked dinner or cleaned in a week and I know my husband isn't too happy with me πŸ˜’πŸ™ sorry just needed to vent...
