so i exclusively breastfeed my 5 week old boy however i have started expressing breast milk with the intention of using it to feed him when i'm out in public like at a shopping center, and also if for whatever reason i need to have extra set aside say for an emergency.
The thing is i'm not finding any info on how to go about transporting it, what temp i can feed it to him, how long it can stay at certain temps, and tips on how to get him started on drinking from a bottle. Should my partner feed him so he doesn't get confused , like he associates the bottle with my partner and the boob with me or is that just silliness and he wont care? We are hoping to only have to feed him from the bottle once or twice a week , but should we do it more often so he gets used to it? and when i feed him from a bottle im supposed to express around that time so my supply doesn't run low right? please help i would like to be successful at this but i also dont want to hinder my supply or potentially harm my bub by giving him off or badly thawed/stored milk.
thank you for any help.
