I'm a ftm and wondering if it is ok to use multiple brands of bottles and nipples if my LO is willing to take them. I breastfeed but I also pump and bottle feed on occasion and my LO will take a bottle at daycare. So far I'm only using one type of bottle/nipple but I have a whole bunch of other kinds that were gifted to me. Just wondering if it will confuse my LO or if it's ok. Thanks!
