Depending on where you're staying, it might be worth checking with your hotel. I've found previously on travels elsewhere that a lot of larger hotel companies have things like childcare or kids club type things set up - and if you're already staying there, you can't really get more convenient than having in-house babysitting/childcare services! If your hotel doesn't offer something like that though I'm not sure where you would have to check with - especially with needing some sort of accreditation or insurance, too. Maybe some other moms or dads are on here that have used nanny services in India before!
