Hi Nicole,
I'm coming to understand just how much your head spins with questions and concerns when faced with the journey we're all on. Nicole, you're not alone in feeling like this, I'm right there with you in feeling 'paranoid' about every little movement or mannerism that Lucy has. I think, is that normal or a sign of something else? Did my other kids do that, what age did they do that, how did they move, is Lucy different? The list seems unending!
Perhaps it's worth asking the physio about your concerns with Sarlett's flexibility. See if they can suggest why it's happening, if it's something that even needs attention or if it will just resolve itself with normal growth and development. Ask them for any suggestions they have for helping Scarlett to feel more comfortable with her legs and crawling etc. You may find after talking it through with them, that it helps to have the info and answers that you seem to be wanting.
I hope that things go smoothly for Scarlett,
Pip.
