are you mixing it together? as in formula and breast milk in a bottle? or just bf and bottle feeding at different times? lol sorry i got confused

I just wanna make sure it's ok to mix because I have been @mommybump3

i do, i have too my son eats too much. he can eat off me for 30 min or so and also drink 3-4 oz bottle.

I breastfeeding feed and formula when I can't produce fast enough
