Hi im traveling to phuket with my 5 mths old baby. May i know: (1) if i can use boiled distilled water to make formula milk? (2) Is distilled water the same as drinking water? It seems like theyre the same thing. (3) can i use tap water (instead of boiled distilled water) to wash baby bottles and breast pump parts, followed by sterilisation? (4) what medication i should pack? Thanks!
