Hi. New mom of a 4 month old here. My husband works from home a desk job as well. I am a stay at home mom. I get up at night. While I get a stretch longer than 3 hours is wonderful, if you’re breastfeeding what can do? At most he can get up and change the baby, allow you to pee and get ready to feed then what? Do you want him to sit up with you while the baby eats? That makes no sense. Am I tired? Yes. But my husband takes over duties on the weekend and I can catch up on sleep. My baby has also started sleeping a good 5-7 hour stretch on the night (at least until the next regression hits) so I get a little more sleep. I understand where you’re coming from at the 50/50 I don’t understand how he can do it if you’re breastfeeding unless you have him give baby a bottle. I don’t really have a verdict here but maybe see if you could work something out where you can nap when he’s done working. I do that when I’m really tired or had a bad night. Good luck.
