Is it suitable to bring a 4months old baby to genting, malaysia? My in law wanted to bring us for holiday but im not sure if just a 4months old baby able to cope the long journey and the environment there.

Its is really up to individual. Some may feel that they are too young to travel as they are still building their immune system and that they are not vaccinated against certain diseases . It is really up to ur comfort level. I feel it would be much easier to to travel with a baby instead of a toddler as baby do not run or crawl around as frequently. Baby also nap more than a toddler. Personally i feel It would be much easier to cope with. As for the baby, bring his or her favourite toy along and ensure he or she is kept warm all the time.
