I am planning a trip to India with my 8 month old daughter. I am worried about her formula, baby food etc.?

She drinks Enfamil Lacto Free. Is there any way I can get the formula, Gerber baby food and disposable bottle liners in Delhi / Lucknow ? It's not possible for me to carry supply for the whole trip since I'm planning to go for around 3 - 4months. I'm also hesitant to change her formula since she has severe eczema. Please advise.
