It took me a solid week to be full-time mom all day every day again (I am a SAHM w/ a 2 yr old and 5 yr old). It was my 2 yr old that physically challenged me. My advice, be as lazy as can be, rest, let your house be dirty, feed them whatever is easiest for you. It was harder than I anticipated, mostly due to fatigue from lack of calories in my opinion. I was off the Rx painkillers in 3 days though and took tylanol. Good luck, it is hard
