Girls, hello everyone! Such a question, is anyone who has been on Cruise or just flew abroad (just no experience in traveling with a child) and doesn't know how everything is organized in terms of laundry, dry cleaning, etc.? How did you wash children's clothes there, in other words, did you take powders with you or were they washed with powders? Just maybe an allergy, so I'm worried ? and advise what you took with you from medicines, things that were definitely needed ? Thank you all for your answers! ?
