Breastmilk to Formula

I started to slowly introduce formula to my 3 month old baby.. Yesterday I did 4oz of milk and 2oz of formula for 2 feedings and she seemed fine.. then I nursed at night and this morning.

How long should I mix milk and formula before giving her only formula?

I plan on mixing 2 more times today and then giving her a bottle with only formula to see how she does.

She’s going to daycare tomorrow and I don’t have any frozen breastmilk left.

I’m a little nervous to send her to daycare with only formula.. I’m trying to pump some now but my supply went down since I started working.

I will nurse in the mornings and at night.
