Wouldn't you think that potty training would be less time consuming than cleaning up all those messes?
I think certain parts of the house should be off limits, closed off to your baby. Maybe keep doors closed, or put up gates. Hubby will do what he wants when you are not there to ask/nag/harrass him constantly, trust me I know. LOL. Just focus on your family crisis now, your baby will be fine when you get back. If you have to retrain she will be even better than before! : )
Hope everything works out for you and your family.
