Absolutley no advice really. I have been to india a few years ago for a few months and did see a few people traveling with young children, about 5 yrs old. But not as young as yours, although im sure people do. I was already quite sick when i arrived (had been traveling in other countries before hand) and actually got a bit better while i was in india. And if you have family who are 'locals' they will know all the good places to eat/go etc and what to avoid! Hope someone comes and gives you some better advice and you end up having a great time, Have you been to india your self?? hugs to you
