Transitioning from formula to milk

Brit

Okay so my Son is about to turn one on the 8th!

So now I’m questioning what’s next for his “milk”.

He’s been on formula since 6 months, now he’s only on three bottles a day. And he has has a very good diet he eats anything and everything so I’m not worried about him getting enough nutrients from his diet. I really never have thought I’d put him on the next stage formula (toddler stage) I always just thought I’d just change him straight to milk. Can anyone share stories of what they did or how the transition went ? Did you do your own thing or go strictly by what your doctor recommended.

My second questions is that I’m tossing up between oat milk or cows milk. I myself don’t drink cows milk, I do eat cheese, yogurt etc.. with cows milk and so does my son. I just for some reason stopped wanting to drink it a few years back (I just don’t think we are meant to drink it, even tho i I love cheese still 🫠) and I like oat milk and I’ve read up on all the nutrients and I believe oat milk would be a very good option for my son, iron, calcium etc…

Anyone else switch to “plant” base milks? and how did it go.
