Anyone who has your child’s number saved in their phone can see their Telegram account and message them through Telegram. When a new user joins Telegram, any user that has your child’s number saved will receive a notification chat to let them know that your child has just joined Telegram. If your child sets up a public username other users will be able to search for them via a contact search under ‘global results’.
