May I know is fresh milk good for lo after one ? Or formulae ?

I would say fresh milk is nutritious. It is very common for mothers in the western part of the world to transit to whole milk instead of formula. What most of my friends did was to first transit to formula, then to regular milk when their children are slightly older. There are a couple who transit to whole milk too. Both options are beneficial to the little ones so it is really up to you (and perhaps how well you baby takes to the taste of fresh milk). Hope this helps! :)
