How to introduce formula ??!!!!! HELP!

My daughter is going to be 3 months on Sunday. She is Ebf. However I don’t produce enough milk when I pump. It’d take me literally the whole day to pump enough for maybe 3 feeds. After this virus I’d like for her to be able to have formula when I am not with her (due to daycare, or other childcare services) and possibly breast feed when I am with her.

Is there a way to go about doing this? How do I introduce her to formula. ??
