I agree with rainbowgardener. I'd be more concerned if the flower bud showed extremely early, but the leaves, especially, should be OK.
(I just had an image of the little tulips crouched down in the ground with their "hands" up in the air, feeling to see if it's time to raise their heads yet.

Then, too, there are different varieties of tulip and daffodils too -- sold as early season, mid-season, and late season. So they don't always come up in synchronized timing relative to crocus or to each other, etc.
When planting in fall, you can choose different early~late flowering varieties so you could have a much longer spring show.
