You will find both on the airplane and in Singapore a very nice atmosphere for your child. Talk with the airline and check out the layout of the airplane. The person you talk to might have some suggestions about where your family would be the most comfortable. Also ask where the larger 'family' lavatories are located. They give you more room to take care of your child without feeling that you are in a telephone booth. In Singapore, both the Night Safari and the regular zoo are nice places to visit. I really enjoy visiting Singapore.

Have a wonderful visit!
