Health visitor check coming up

Had a letter from the health visitor this morning that my daughters 8-12 month check is on the 9th of Jan. And then they come back at 12 months again... Nottinghamshire is weird in how they do it. Anyone else had their letter yet? I feel nervous and I don't even know why. My little girl is doing really well, 4 teeth, babbles all the time, can sit up, is really happy and smiley, sleeps well, eats pretty much anything we give her and she's getting closer to being able to crawl 😂
