I can't believe she's 22 with 4 kids! She had to be 13 or 14 when she had her first. I'll be you she's just looking for a babysitter. Gee, what can I do so that I won't have to take care of my children? Gee, the military would be the only place that I would NOT BE allowed to have my kids! Honestly, I wouldn't do it. I'd tell her to get her act together and get a job and take care of her children! She needs a serious wake up call (or Dr. Phil!) You have to think of what's best for the children here. Is it not having a mommy for 4 months (and probably longer)? I don't think so. How could anyone abandon their children for that long? If you love those kids and feel she's a bad mother, then I'd say the only way I'd do it would be to demand PERMANENT custody. She needs to have her tubes tied and not be allowed to reproduce.
