Congrats!!!
Yes, check every day, carefully, sitting on the ground over a soft surface or with the nest box still on the floor of the mom's pen/cage, as they can be quite squirmy and just try and pop right out of your hand. I would make sure to wash hands first with an unscented soap. Then check twice a day(at least). You want to make sure they are being fed, so aren't dehydrated and wrinkly, that at least once a day they have a nice full milk belly, though sometimes it can be tricky to figure out the exact time mom is feeding them. Once or twice a day, usually either early morning or late evening.
If by 24-36 hours they haven't been fed and are wrinkly, you will probably need to intervene. Though holding them to mom to nurse is the best way, as hand feeding formula carries an extremely high risk of aspiration pneumonia occurring, which will be fatal if it happens. If you have to assist holding to mom, it needs to be done carefully and preferably with a helper, as you don't want them to get kicked or thrown if mom struggles.
Make sure to work mom up to unlimited or close to unlimited pellets, preferably alfalfa based pellet, free fed a grass hay as well. They need a ton of calories for nursing, usually 3-4 times the amount of food they normally get.
And enjoy the experience. They grow up so fast!
