My son stopped drinking formula at around 12 mths he started to refuse it around 10mths but I kept with it I switched to a toddler milk but he didn’t like it so he now drink cows milk.

We started at 12 months

Cows milk from12 mths is fine

It’s been so long ago now that I cannot remember when I stopped using formula. I would seek the advice of a community health nurse.

Maybe consider switching him to cows milk now (provided he isn’t allergic). He could still eat all 3 meals and snacks as needed – you could just give him a cup of milk as well when needed.

I’m switching between milk and formula now. He eats well but if he seems off his food when teething or after his latest immunization then formula is increased.

if he is eating well, you could ditch the formula.

Following this as i have the same question

My daughter went straight from formula to cows milk at 12 months

I breast fed my daughters between 16-21 months so they had cows milk after that.

At 12 months old, my daughter switched from formula to cows milk. No problems at all.
Will be doing the same with my son.

My kids never had formula. They went straight from breast to cow. Good luck with your choices

Mine never had formula at all – if children have a broad range of healthy food then they should be getting what they need from that. You could always try cows milk and see how it goes.
