I'm tired 😩

3 weeks today and she has been the best and easiest baby. Even took a 6 hour road trip and she slept the whole time and only woke for feedings when we stopped. She was sleeping 3-4 hour stretches at night and now shes up every 2 hours and that's if she even sleeps because for 5 hours now even though I fed her twice she still wants to suck so I've had to keep the binky in her mouth which she never needed before and idk 3rd kid and I'm dying here. Rant over.
