I have crate trained mine,for not just the reason of potty training, but also for the chewing. We just recently remodeled my bathroom and had them confined in the kitchen and bathroom area one day. I put newspaper down in a corner for them to potty on (they chew up pee pads). We came home and found pieces of wood everywhere. They chewed up my brand new molding on my shower. Then another day they chewed up my cord for my DSL.... without that cord I couldn't come online to YT.....
Anyways my point is, I think at first it is a little easier to crate train them. My husband and I both work 8-5. Either one of us do come home at lunch and let them out and then let them run around for an hour. Then they get put back in there til around 3:30 when my daughter gets home from school. Next year it will be an hour earlier.
I don't think,by me working, that I'm not a good momma to my babies. They get tons of lovins and play time when they are out of their crates.
Also for the last 3 weeks, we have let them stay in the kitchen during the day. Since they are older they doing alot better not chewing and peeing all over god's creation.
