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.
This allows her to play with the toys and practice supported sitting, which will be more appropriate for her at this age than actually being placed in it. Wait to place baby in exersaucer until he can sit independently, without having to use arms for balance (typically around 6 or 7 months). Most play saucers state they can be used with infants as young as 4 months.
