2) Upscale stores like Just Moms on Bhulabhai Desai Road in Bombay and others in major cities stock all imported baby brands such as Mustela and Aveeno, in addition to Nuby and Avent feeding products. In addition, department stores stock brands such as Pigeon and Johnson and Johnson and local companies such as Himalayan Concepts do wonderful organic lotions and powders for baby that are well-suited for Indian weather. Unless your baby has sensitive skin, don't be afraid to try local!
3) Food-wise, it's always possible to get a butter naan, plain dosa, or rice if you need an emergency meal. As long as food is cooked, it's generally safe to eat. I would stay away from canned food because I have only seen Heinz available and they are usually not stored in a way that would preserve them well in the Indian heat. When all else fails, there's always chicken nuggets at McDonald's.
4) Always check the seal on your mineral water to ensure that you have a new bottle. In fact, whenever possible, I would boil Karam's water just to be safe.
5) Car seats are few and far between. Look around you: families of five are making their way around on scooters. Just hold on tight and avoid auto-rickshaws and trains if possible.
6) India is one of the cheapest places to buy books, from as low as 50cents. Toys are cheap too but if you're anal about plastic, be aware that this isn't the best quality material.
7) Always use a mosquito repellent when outside for extended periods of time. Malaria and other insect-borne diseases attack the unsuspecting in India.
