Like every 3-5 days switch the ratio of Breast milk and formula, if you notice constipation, diarrhea, gas... Go back to the previous ratio wait another 3-5 days and then try again. Do it all gradually

@smileymommy, yep I was gonna say what @ashsloan said

@smileymommy, you'll want to mix it at first and slowly get more formula instead of breastmilk. If you switch cold turkey it could cause a lot of digestion problems.

@mommybump2016, @mommyagain

she is just now starting to successfully drink out of a bottle and not chew on it! should I mix breast milk with formula or give her strictly formula with the bottle?

Gradually take one feeding session away a day

@smileymommy, oh ok and not really in all cases have you started her on a bottle? Might have to pick several to see what she likes and feed her less from the breast and more from the bottle or let her nurse only at night

I don't have to but I'm planning on starting school full time within the next few months & I heard it can take awhile! @mommyagain

Do you have to? Can you wait awhile to see what baby does? I'm asking because my daughter ended up weaning herself at 9 months
