Congratulations!!Don't fret about the sewing space. Many (and I mean many) moons ago when I was in my baby years (there were three very close together). I first was in the utility room then was sqeezed out by a new chest type freezer. Then I set up in our bedroom on a card table. Remarkably the babies slept through the whirrrrr of the sewing machine. Now I'm sewing in the room that was once the girls' room and it is so cluttered with stuff that I do my machine quilting on the dining table. You can sew anywhere, as long as the "mess" doesn't bother you. Just keep the sharp things, tiny things like bobbins, hidden from the baby. You'll be fine. Remember to enjoy those years, because before you know it you'll have lots of room to quilt and that baby will be all grown up. Enjoy!!!
