Hi
Glad that all has gone well. They are very cute!
It's difficult to say yet, to be honest. There is a little rexoid in there but they may rather be a cross as the hair is more loosely wavy rather than tightly curled. You will have to wait a little to see what happens; the rate at which the hair is growing out over the coming weeks will show whether you have babies on the long-haired side or not.
Mixes can be full of surprises; it is what makes them so unique and fascinating.
Have a look at the little teddy newborn in my video guide for comparison. His two brothers are smooth-heired cresteds.

Here is a picture of my Triplet adoptees as babies at the rescue; the two lighter ones have teddy in them:
This is how they were looking when I adopted them at 8 weeks old:
I think you may be a bit more likely to end up with babies looking like Myfina, the larger ginger and white baby on the right, who was a cross of smooth/American and teddy (?) with a half-hearted aby rosette on her other side.
The tiny baby had stronger curls and more of a teddy inheritance; she is a cross between teddy (or something rexoid) and aby and at 8 years the only one still going although sadly pretty frail now. The third, black sister, is a smooth aby cross. Their highly pregnant mother in a very bad state was rescued from a 'sanctuary' that was breeding indiscriminately from rescued animals. It takes a whole lot for a guinea pig displaying three breeds on one body or getting three different breeds in a litter; normally it is just two breeds in play.
