It's hebrew, Matan means gift and Lev means heart.
We had about 60 people in our house for the circumcision and naming today, and I'm completely exhausted, probably overdid it - and have had more pp bleeding today than the past 3 days combined. Thankfully DD went to bed at 6:30, and I'm taking an early bed time too!
Sounds like quite the celebration. You know, I have always had my bleeding pick up right around the one week mark with my last 3 or 4 as well. I think it does have to do with "feeling a lot better" and over doing it. Certainly with a party going on that would be easy to do. I hope you are able to get a good nights sleep!
