Blogging with a baby is not easy. I've learned to balance baby on one knee while he is napping while balancing the laptop on the other knee.
Learning to type one-handed, with a minimum of typos, will take a bit more time.
NOTE: Before I get a slew of cautionary comments, tummy sleeping while closely supervised is okay. At night he sleeps on his back, even though he'd much rather be on his tummy.
