If you had a really short maternity leave, how did it go?

I'm only planning on taking 4 weeks for Sister, which is starting to really get to me. I only took 7 with L, which wasn't a TON, but a 4 week old baby and a 7 week old baby are totally different.

I'm 100% happy with my daycare choice, and I know that Sister will get tons of love and cuddles, mostly worried about my emotions. I typically work more than 40-hour weeks, and I imagine that I'll be cutting down to the bare minimum 40-hours after I go back for a couple weeks.

Just wanting to hear about experiences from people - good and bad!
