Alternatives

Hey, so my daughter recently turned 1 and we are down to the last couple of tins of Alfamino and will not be prescribed anymore. We’ve been putting oat milk into her formula and this morning I gave her a little cup of oat milk on its own (she’s had it before on its own) but today starting gagging and brought it all back up. She’s never ever done this before. I’m not really sure what else I can offer her as she can’t have almond milk due to other reasons and can’t have soy as she’s allergic. I’m panicking she’ll not get enough nutrients as she doesn’t eat a lot either🙈 I’m a FTM so feel completely out of my depth!! Thank you x
