One pumpkin ripening lots of small ones growing.

My squash patch is overgrown but I did clear leaves around the biggest pumpkin, about the size and weight of a medicine ball.  The other squashes, sweet dumpling and butternut have no fruit they have had lots of flowers but nothing to call a fruit yet.  Should I cut my losses and clear out everything bar the pumpkins?

Thanks the purpose of growing my own was to try teach a 46 year old patience.
