I have a few early ones with buds on, but they are not newly planted. I am just looking forward to seeing my Spring flowers. Last year I was in Australia, and missed them all. It made me sad.
As others have suggested, leave your daffs for a little longer, then gently investigate to see if A) they are still there, and B) if they are showing any signs of life. If they have failed you can buy ready-grown ones in pots at most gardens centres and markets to give you a show for this year.
With reference to snowdrops. I tried, for years, to grow them from bulbs, but they just didn’t seem to like my soil. Then a gardener friend gave me a few clumps that were already flowering. I planted them, and they have come up successfully every year since then.
