Eh I totally get it, a few of my mum friends who are pumping have done this! Your pump machine boleh bawa dalam carry-on, just declare it kat security and they usually cool dengan it. For susu, bring a small cooler bag or thermal bag dengan ice packs, and most airlines allow you to keep it in the cabin if you explain it's breast milk (they're usually very understanding about this). One of my friends swears by bringing those disposable sterilizing bags and pump parts in a ziplock in her carry-on so she can pump during the flight if needed, then store the milk immediately in the cooler. Kena pump regularly to maintain supply jugak, so think about how many times you'll pump during the trip so the hotel or wherever you stay ada proper space to do it. Safe travels, mama!
