1 year well check

Yesterday I took Adriana to her 1 year well check with her pediatrician. It all went well she looks good and is growing both her height and weight. The only concern he had was her head size. He said it has not grown much since last time he saw her in Dec. In Dec it had a circumference of 40 and now in March its 40.5, so it has only grown .5 in 3 months which is not what it should have grown. Of course her head will be smaller compared to other babies but it should be much bigger than it is now. He thinks that maybe one of her sutures in her skull might be fused together. The sutures are the parts where the skull brakes apart, well divides so your brain can grow as you get bigger and eventualy close when you are an adult. In Adrianas case it should be open but he would like to have a ct scan of her head to see if it is fused or now. He said it might just be nothing or it might be something, he didnt want to jump into conclusions but of course it's something that has me worried. She has enought to deal with now and to just add something to her would not be ideal. I have so many things that I do right now that I don't even know how I remember to do all of it but I just do. Hopefully it's nothing and she's fine but I will update as soon as I know.
