What kind of bottles do/did you use?
*Did you use a bottle warmer?
my daughter likes the nuk bottle the best. no bottle warmer... seems like it be a pain. 30 seconds in the microwave works just fine!
We used Medela wide nipple bottles at daycare.
Dr. Browns worked best for us. Love them
We use bottle warmers, unless we are visiting or camping, then they go into a mug of hot water.
