Chirel, are you going to be a SAHM(stay at home mom)?
, you will have odd moments in your day to craft... like during you lunch break, the commute to/from work, that extra hour before you pick up your kid from daycare.... so portable crafts are key (as mentioned: knitting, crochet, embroidery, etc).
, you should craft when you have the time- most likely at night (like mentioned by SpunkyGal). You have more options for craftiness, like sewing and book making.
I am a SAHM and I have 2 babies as well as a 7yo SS, three kids! When my 2yo was first born (and is the case also w/ my 3mo) I put him in his bouncy chair or car seat and had him in the room with me while I was sewing- after awhile the sewing machine sounds would put him to sleep. With the arrival of the new one, I've begun opting for more portable crafts like knitting... something I can work on here and there and bundle up in my diaper bag if need be. With both babies I didn't stop crafting, just found different crafts that could fit in my time restraints and needs. I took naps w/ the babies (but not every time or I'd be sleeping all day) and breastfed both. Sometimes their Daddy will help out by letting me have an hour or so to myself. Getting a mental break from newborn duties by crafting was an essential needed release.
Also I'm assuming you're a first timer, so I'll give you some tips that I've learned:
-When baby cries you don't have to sprint/run/fly to her side immediately, baby can wait a minute or two or three (my MIL taught this to me) for you to finish that knitted row. This is the hardest thing to overcome in first timer motherhood
-You can get a bouncy chair or a car seat with a rounded bottom, while working on things if baby gets a little fussy you can rock either seat with your foot to calm him (when your baby reaches toddlerhood you'll have the ankles of a god)
-If you are breastfeeding, you can do stuff with your free hand (the one not cradling the baby) like draw, paint, or read a book.
Congratulations on your upcoming new addition!! When your baby arrives, post pics
Right now you have time to make baby stuff before it's born, so get crafting lady!
