11 month old refusing his bottles

[Littlesparrow0]

My little fella turns 1 next week. He usually takes two 8oz bottles of formula for me. One in the morning and one at night before bedtime but over the last 2-3 days he's been refusing his formula. He's eating solids fine and drinking water fine but pushing away his milk. I've even tried putting it into different cups for him but he just continues to push it away.
I've now tried to start him on full fat cows milk to see if he'd perhaps take that at least for me but it's not a winner at the minute either.

I'm not sure what to do and I'm scared now that he's going to lack in nutrients. Any ideas on why this is happening or advice on what I could do? He used to be so good at taking his bottle, this has literally came out of nowhere!

From 1 year they only need the equivalent of 300 mls of milk. This is inclusive of milk in cereal, yoghurt, cheese, etc so doesn't all have to be in drink form

So I don't need to give him extra vitamins etc due to him missing out on his formula, just ensure he's getting extra dairy products?

Sorry I've been panicking that he's going to lack in stuff now that he's refusing the formula. He's my first baby

If he's eating solid food and drinking water then he doesn't need formula. My dd weaned at 6 months was eating well and hated her bottle so we just stopped. She's in the 95th percentile for growth is a healthy weight and has a good relationship with food. I wouldn't try and force him.

All babies up to age 5 should take vitamins A,C and D. If they take over 500/600 mls of formula they don't need to take them as formula is fortified.
