Constantly worrying

Not sure if I am the only one but I am constantly worrying about how my child is developing (she is developing well just to clarify)

Im a FTM with a soon to be 6 month old and I feel like ive become so unhealthy with always thinking too much about what she can and cant do. I observe every little thing and then if i see something she does but havent seen other babies do I worry thinking something is wrong and literally google it 😣 and then what do you know im here stressing out some more 😩

I know all babies develop at different rates but I just cant help but stress. Are most first time mums like this?

Naturally im a stress pot and with a baby I am worse + sleep deprived because I have no family to help me when I need.

Anyone have tips on how I can manage this or any words at all to put my mind to ease. Im exhausted physically and mentally 😢
