Seems unwise to give your child’s early life story to any of these companies, especially when mapped to a network of her relatives and likely including photographs which people may not be as diligent to keep private as you.
Your daughter cannot consent to this, and it is your duty as parents to protect her privacy until she is old enough to decide for herself what to share and where.
