Toddler jumped on belly

So I'm a nanny for a 15 month old, and she just sort of jumped on my belly harder than I would have liked! I know baby is super well protected in there, but should I be worried? I can't feel baby yet, so I won't be able to know if he's moving less. Obviously if I have pain or anything I'll call dr but just was curious if anyone else has any experience they can share! Thanks!
