Hm. About a month, I suppose. When my daughter was born, she had colic for the first six months of her life, so she screamed for a solid 10-12 hours per day (broken up into intervals, of course), which was most of her waking hours. My husband deployed when she was 2 1/2 weeks old and we had just moved to the location about a month earlier, so we didn't know anyone yet. Anyways, taking her out was a nightmare because she'd scream the whole drive there, the entire trip (grocery shopping, errands, etc.), then the whole trip home. And there was no one to watch her so that I could run out, so yeah. I lived off of delivery food and ate through everything, all cereal, canned food, etc. in the house. Eventually, I got to the point where I could make a quick 15 min grocery trip and just muscle through the screaming. I always felt terrible for the people around me, though, so I still didn't go out every week.
