I agree with VP about getting your dh to take time off and getting out of the house every day.
Unlike VP tho I had 2 under 2 with no daycare and now I have 3.5yo with me FT and my baby. I have insomnia atm so running on 2-4hrs sleep most nights. DEFINITELY recommend leaving the house every day. Also recommend exercise to keep you going.
Lots of hugs lovedy.
