Aaaah Honey, I'm so sorry to hear that, it is so hard and tiring. I also do the lion share of the child stuff for the same reason and also that DH ends up just chatting to Sam and making things worse, no common sense to be honest, most the time
What do you think is going on, is it the cold and teeth causing these NW's or do you think it's a combination of that and OT
(HUGS) for you Sweetie.x.
