Here is the link for the guidelines of what you can send to your sponsored child: https://www.compassion.com/letter-writing/tips-for-mailing-small-gifts.htm Other than that, if you are in-country you can take items to mail to the country office (get the address from Compassion) and then they will be delivered to the child. Or you can set up a visit to the child and take things with you to give them. Sometimes you can send a small gift with another sponsor who is going to be visiting their child and they can give it to the Compassion representative, who will get it to the correct child.
