Make sure that it is tagged properly at check-in. You will need either the pinkish KL version (Gate Delivery) or the greenish AF verision (Delivery At Aircraft) - or maybe a local IAD version.
Be prepared to wait a while at AMS as they offload the other luggage first and then put the trolleys at the top of the stairs, mid way the airbridge.
Only complication may be if your reference to 'layover in AMS' means that you're transfering, in which case you would need to gate-check the stroller for the connecting flight.
(Hope this is not too late yet)
