Just started introducing solids to my 6 month old. when you go out for the whole day on weekends, would you bring the puree food out? or just feed breastmilk for that day?

As for me, I will not do fruit puree for that day. Fruits oxidize faster so will turn sourish fast. I brought baby cereal and then warm up either bm or FM to mix with it. As they are still young, I prefer to give them fresh food. You can choose to bf the whole day if it is more convenient for you.
