I don't have twins in my arms (yet) but will soon.I am going to suggest something that my sound a bit obvious and a little "easier said than done". Try not to stress out. Have fun, laugh with your kids. Some things really can wait. The world will not end if we leave the dishes for an hour or two. The sky won't fall if we don't make the beds today. The cleaning can wait sometimes. We are not "Supergirl" and shouldn't try to be.
I found when I started to chill out about things that weren't really that important, life became so much easier and more enjoyable.
Sorry if you think I'm making it sound too easy, but it really is.

Sending you big hugs and best wishes,
Debbie
