I wasn’t as diligent about sleep training w him like I was with his older sister. I have such anxiety that he’ll wake up his sister if I let him cry a lot and also I’m so tired I just end up getting up to feed instead of following thru w the training bc it’s faster in the short term. We went thru brief periods where he’d sleep thru the night but then it was back to getting up once or even twice. Now he’s been getting up twice AND early & I am EXHAUSTED. Any ideas, solidarity? He eats a ton of food, still BFs. Have the same routine everyday for nap, bedtime (we’re very consistent w that). Should I really try to sleep train now?
