My baby is going on pee pads in the garage. He is doing really good with that. I have a exercise pen that i have made really little for him to stay in at night and when we leave. I had to fix a top on it because he was getting out of it some how. The trouble is now is that he wants to get up in the middle of the night and go out and do his job. Thats fine I take him out and he does it and i put him back in it and he will go back to sleep. But when I leave him in it to go some where he will make a mess in it sometimes. I am a stay at home mom and lots of days i don't go anywhere so i will leave him out all day. Should i put him in it anyway on the days i am at home all day? Should I get a small crate? Will that be better that the exercise pen ? And would it be better to just leave him in the utility room with a pee pad when we are gone? My daughter plays basketball and we are gone at sometimes about 5 hours or so at a time. He is 4 months old and he really likes my lap.
