Hello,
DS (15 days) sometimes gets formula in the night. This is always after and sometimes before a BF as well - it's an addition on his extra hungry nights when he gets too tired to feed properly and too hungry to sleep properly.
So my q is, if he's getting the 'normal' amount of breastmilk and then formula on top, in theory my milk levels should remain unaffected by the formula top up, shouldn't they? The prolactin's getting its prompts at night as I'm feeding the usual amount, and it's not that my milk dries up so he can't feed, it just doesn't satisfy him sometimes. I often check when he pulls off and there's always more milk still available if I squeeze.
Just to say, very gently, that FF at night has been a godsend some nights and I don't see us removing it as an option. We use a syringe rather than a bottle and teat and it hasn't affected DS' BF style, which has always been excellent.
