Even though you are already happy about the birth of your child, I think it is not necessary to display a photo of your baby in full because this is a public space for fear that the photo will be misused by irresponsible people.
You know, your advice on not disclosing the baby's imagery got me curious and I had to go the length of inserting the necessary codes to the provided link and it appears OP already took to your advice. That's evident of some good learning on the part of OP and that's great.
I might say, he's just a baby an facial looks in 18years would be very unrecognisable from what it is now which makes the need for privacy in his case overrated but, what do I know.
Don't want to over think it but, other reasons might as well prove it useful to maintain privacy.
I think it's great that you are so confident about investing in bitcoin for your child's future, but you have to think about the risks and other kinds of hurdles however normally the need for a baby is very great unless you can cover that need from other income and when it grows up.
That's definitely something worth doing and parents should be doing. Other than picking some fixed deposit in on there kids, some Bitcoin investment might be useful and would be worth more in 18years.
Best way to keep yourself from it, view it as not yours because, it literally isn't and never try to borrow from it for any reason as it constitutes your child's future at OP.
