potty training 21 month old am I this lucky??? Advice please!

[SliverCheer]

Hey all!

I've started potty training my 21mo ds. I work from a home office so he spends the day in the office with me, I had tried potty training a month back but I couldn't spend the whole workday in the bathroom with him so I brought his potty in the office. I don't use pull-ups and have just been letting him be naked so he can feel when he has to pee. Yesterday he would start to pee a little bit but stop himself and then we'd go to the potty, he used it 9 times 3 of which he went on his own and used it without me telling him to. Today he's gone 4 times already and I only told him to go 1 time! He has had no accidents so I guess he can tell he has to go then goes to the potty and uses it!!!!!!

I can't believe he's doing so good! At home though he doesn't seem as interested, I guess because he's not confined to the office and has free reign of the house.
Any advice for what my next step should be since he's doing so good ?
Is it normal he's doing so good? He's hardly even talking yet just a few words (hi, cheese, dog, bye, go, hat)
What should I expect?

Thanks!!
