I couldn't breastfeed my tiny little bundle of joy. She was too small and I was too big. Anyone who harrassed me got the finger
Anyway, having had three babies, the last of which was a late-age suprise, I have only a bit of advice:
Slow down and enjoy those three months. They'll be over before you know it, and you can never redo them. Don't worry about things like keeping the house spotless or folding laundry or weed-wacking the yard....romance the baby instead. Hold him/her, get to know every unique thing about him/her, talk, sing, rock him/her endlessly. Take naps when he/she does and enjoy his/her waking moments.
Bond. Enjoy the precious time.
