My milk didn’t come in until 7 days pp with my first, by that time I was emotionally done, nipples were raw and scabbed (daughter was latching but there was nothing there for her, I tried hand expressing also) and already invested in formula.

I want to try again this time.. (due in 2 weeks)

Can I formula feed until my milk comes in?

Is it okay to use a syringe (like you get with medicine) instead of bottles to avoid nipple confusion?
