Rarotonga, Cook Islands, beautiful place, we travelled with our then 12m old, and the car seat regs are pretty none existent over there. Recommend staying somewhere self contained as it makes everything a lot easier
We’ve been to Malaysia, Singapore and Europe with our daughter and we found Singapore the easiest. Not too long of a flight (7 hours), such an easy and walkable city, lovely people who love babies and didn’t need a car seat x
We've done Bali twice, once with a 8monyh old, second time with a 12 week old and 2.5yr old
I went to Europe (uk and Paris) London was amazing - Edinburgh had lots of stairs and cobblestones but we just put bub in a carrier and was fine, same with Paris… if the accommodation is within 500 meters of a train you can avoid taxis & if you can pack light (try to keep it to 1 suitcase and a backpack) your husband won’t want to murder you like mine did 😂 😜
