Your typical umbrella strollers with extremely thin fabric are not recommended for infants due to the lack of support that is provided. Once the baby is capable of sitting upright on their own, usually from 4 to 7 months of age, then it is safer to use an umbrella stroller with less padding.
It depends on the stroller and the child. Some strollers provide more support than others. Just try it around the house and see how he does. Otherwise, it just depends what you have and how badly you need a stroller once you get there. You can always check your bigger stroller, and carry/wear the baby onto the plane. 07/30/2008 15:31 Subject: How old does baby have to be before I can use an umbrella stroller?
