There's no right or wrong way to switch. Ive switched both of my boys cold turkey with no issues. If you want to transition do you want to do it over a couple days or a couple weeks? If you want it to be short just start Friday afternoon when you get home and be done by Monday morning when they go back to daycare. If you want to spread it out then yes it will be okay to sit in the fridge for the day. Or just switch to full milk a day your home and see how they take it, if they don't like it then mix formula in and make it slow
He has 10 days until he is one
I was mixing for like 2 days then I just did cold turkey because my auntie told me she did that with my cousin and I was being generous mixing my breastmilk with the cows milk
Yes because I think formula last like 24 hrs in fridge right ?
