I want to start formula milk which is best for my 6 month running baby boy because I have to go to my job.

A. Hello good evening !! If you have enough milk production then you can express out breastmilk and feed through bottle. You can store breastmilk until 8 hours in freezer or 3-4 hours in normal room temperature. If you don't have milk supply then start formula milk every two hours semi solids once a day. Consult Paeditrician for formula milk suggestion with all nutrients and DHA, ARA elements.
