Its been two days since my girl had her babies and everythings going well, i have obviously kept my male away from her for some time now but  she keeps going to the door that leads to his kennel, is it ok for me to let her outside to see him.

Yes, but keep at least one of them on a lead at first. If she wants to see him, then she is obviously missing him :-p  It might stress her out more if she can't see him. Also make sure that he can't get to the puppies unless she lets him.

Be aware he may well believe she is in season as she will still be bleeding, so he may pester her.

Henry was desperate to see the puppies when Ellie had them, we kept him away for a few days just because he's so clumsy and also of course to let mum settle in with them, but she was quite happy to let him pop in to visit. :-)
