Is my 10-month-old's development on track?
Question:

I am raising two children. My daughter is 4 years old. My son is 10 months. He is not crawling. The difference between them is 3.5 years. But the feeling and state is like becoming a mother again for the first time.
I recently noticed that he is more right sided. He can eat from a spoon. Little by little, he discovers the joy of movement. He really likes water.
I suspect that difficult experiences I had while I was pregnant had an impact on his development (he had a pinched nerve in his neck at 6 months ). It seems to my husband that he is a little slower than his sister. My experience shows that boys mature a little slower and that is neither bad nor good. That's just the way it is. However, I don't know how to help him grow fully further - self-confident, brave, independent...
It scares and obliges that the first year of the baby is the most important... How not to miss it...
Maybe you can give me some advice on how to help my son grow up? There are only girls around...
