You can use the formula which suits your baby. In my experience, nestle is the best.

Weight gain is adequate. You can continue the formula which the baby is accelerating well. Continue which is suitable for your budget.

Firstly you should avoid using formula feedback to baby . It's not good for the baby . 1 st 2nd 3rd and last option is mother milk . Since you are allready giving formula milk ..thn you can use any, but again it's a warning for the baby.no peds suggest formula milk.

No formula

There is no best formula. The formula which suits the child is the best. Lactogen stage 2 is cheaper than the other 3.

Greetings Your baby's growth from a birth weight of 2.6 kg to 7.9 kg at 10 months is completely normal and healthy.At 10 months old, your baby should be transitioned to a Stage 2 follow-up formula suitable for infants aged 6 to 12 months.Highly reliable, widely available, and budget-friendly alternatives in India include Nestle Lactogen Pro Stage 2 and Lactodex Stage 2, which are significantly cheaper than Nan Pro, MMS, and Dexolac.

lactogen stage 2 ( milk only 3-4 times in 24 hours ) rest you have to give solids ( khichdi / daliya / sooji / fruits ) kindly dont be dependent only on milk

Lactodex stage 2 and Lactogen stage 2 cheaper compared to other brands

At 10 months, if your baby is tolerating the formula well, gaining weight, and has no issues like allergy, constipation, excessive spit-ups, or poor growth, there is usually no need to keep changing brands. Nan Pro, Dexolac, and MMS are all acceptable infant formulas. The best formula is often the one your baby tolerates well and that is affordable for your family.
