Hi mama! Sa 10 months, okay na siya uminom ng regular cow's milk like Dutchmill, pero mas recommended pa rin na maging main source ang formula or breastmilk niya until 1 year, pwede lang siya mag-try ng cow's milk as part ng meals, hindi pa as replacement, kaya siguro better talaga to check with her pedia about quantities at frequency so sure ka na okay sa kanya!
