So my son is due October 10th but we think he'll be here mid to late September. I'm already thinking Halloween costumes because I have a 7 year old step son too. I want to do a family costume. The one I have in mind is for three people but could be four. The 7 year old wants to be something scary and doesn't want to dress up with the rest of us and my husband said that he's not dressing up if his son isn't going to dress up with us. I've given up so much already to include his son into our life that I don't see why I can't have this one thing.
