Hindi ko inirecommend yan, mamsh, better to keep breastmilk separate sa freezer para safe at walang cross-contamination mula sa ibang foods, lalo na kung may meat or strong-smelling stuff doon. A few of us mums ang nag-dedicate ng separate compartment or even small cooler para sa pumped milk, parang treasure natin yan e haha, sobrang mahirap ang gutom process kaya gusto nating protected talaga. If worried ka sa space, pwede mo ring iclarify with your pediatrician kung okay na talaga together, pero sa karanasan ko at ng mga kaibigan ko, it's safer to keep them apart!
