Hairy babies πŸ‘ΆπŸΌ

Amelia β€’ 25, been with OH for 9 years in April, my son turned two in September and I'm expecting my second son 23 Dec 15 πŸ˜ŠπŸ’™πŸ‘ΆπŸΌ
Hia guys just a quick question 😊 My first baby was born with a good mop of dark hair, same as me and his dad. What are the chances of my second born having hair too? My cousin had a baby boy without any hair and has not long had a little girl with thick curly hair so I know it can depend but just wanted to see if anyone had any experience with this Xx
