Congrats!! Has he nursed yet? Nursing will release hormones that will help her to pass the afterbirth. (But, just for fun, some does don't want their babies to nurse until they've passed the afterbirth) You could hand milk her a little bit to speed things along.
If she only has one kid you could/should milk some colostrum and put it in the freezer in case you ever need it. If she hasn't passed the afterbirth after about 6 hours I'd be calling the vet for an injection of oxytocin - but I'll betcha she won't need it and that things will go as nature intended! He's a cutie and we will require more pics!!
