My girls:
6 mos and 3 pounds
2 years and 4 pounds
both hold it overnight with no problem. During the day they are out at minimum ever couple hours. But after playtime, lots of drinking, running around, etc.. they go outside.
If you are going to be gone 8-9 hours during the day, for your baby's sanity, I would get an x pen and put pee pads down. Theoretically he could hold it that long during the day, but if he has to turn around and hold it that long again over night, that would be hard on his bladder I would think.
Good luck and he's a cutie!! |
