Spring blossom

Which type of spring blossom I'm not sure. Any ideas? Other than this have been indoors all day with little boy who only wanted to snuggle or sleep or spit his medicine out at great velocity, but better than yesterday. Our fantastic childminder offered to have Carys after nursery instead of William today, so I didn't even have to go out to get her. Lovely although cabin fever was setting in by the end of the afternoon.
Hoping he will improve again overnight so I can get out tomorrow but that will only happen if I can get the monkey to go to bed, he has had a late evening revival and is currently racing round the kitchen!
