Can I put DD onto cows milk 13 days before first birthday?

[Mummyhug]

DD is coming up to one year old in 13 days.
She breastfeeds first thing in the morning then has formula for a mid day nap and at bed time. I don't have any plans to drop the morning breastfeed but we're down to the last bottle worth of formula and I'm just wondering if it's worth buying more formula to take her to her birthday or can I go onto cows milk now?

Oh mummy, these are just guidelines. You can make your own decisions.

Good luck! She'll be fine whatever you choose.

Absolutely fine

A week before her first birthday, DD completely refused to breastfeed ever again. I gave her cow's milk in a sippy cup. She took a while to get used to it, and her poo was a bit funny and grey, but within a couple of weeks she was fine with it.
