I just kept taking Luigi out every couple hours or soo and would not bring him til he went peepee or poopoo. And we would take hi m out as soon as he woke up, 20 mins after he ate, right after we played alot amd always right before bed. And during the day, every 2 hours or so. I think he got the hang of the repitition, cuz 1 day he just walked over to the door and looked at me like-- well, whatcha waiting for??? I think he just got it. So try to get him on a schedule and stick to it!!! And repitition, repitition, repition!!!! And always praise her with lots of love and attention when she goes outside!!!! Luig was about 4 monthes when he got the hang of it!! And he's like clockwork. Another thing I did was to get super excited about going outside, and he too got excited!!!! So I tried to make it a fun thing!!!! 10 weeks is still too young to get it right away, but she will soon!!!!
Good Luck!!!!
