Frustrated today

do

So I'm a sahm married with 2 babies under 2. An 20mo and a 3mo. My husband truly is an awesome father and husband. He takes care of us and helps with the kids when he is home but he truly just doesnt get it. How hard physically and mentally being a sahm is. He doesnt understand why I cant get a nap or why I'm upset that i cant get housework done some days. He is helpful but he has zero empathy. While i know feeling overwhelmed and frustrates is normal and ok it would be helpful to have it validated.

The baby sleeps great during the day the toddler sleeps great at night. Soooo I'm up at night with baby bc my husband is either at work or I'm trying to let him sleep and then the toddler is awake all day with the exception of about a one hour nap which I use to do everything I cant do with him awake.
