Hi Sarah, frogs tend to slip in and out of winter torpor, which isn't hibernation as such. So your frog might go back to sleep again with all this snow. I think generally all hibernating creatures will emerge later this year than other years as it's been so cold. I certainly haven't seen any bumblebee queens yet, last year there were loads on the wing by now (where I live, anyway). I would definitely put food out for your hedgehog if you see it out - as it will be starving - but otherwise don't, as it might coax it out of hibernation early. That's my guess, anyway.
