Having 8 total (mine, hers and ours) it's pretty easy. Leave them and don't think about them till it's time to pick them up. They will be fine. It will help their speech, help them socially, and emotionally. It's a good thing. Next thing you know your little baby girl (in my case) will be shipping out to Texas for 8 weeks with 7 months of tech school (or whatever it's called) as Security Forces with the Air Guard. . It goes by really fast.
