Kyssy - Congrats on a new baby! Your life will change dramatically, but I'll bet that you'll find time for sewing during nap time!
I don't get as much sewing done in the summer either. I have more outings because of the nice weather, more yard work, more company coming to visit. But I still think that there is nuthin' better to cool down and gather your thoughts than taking a sewing break. I remember when my kids were young that I'd be busy for a month in the summer making school clothes.
