I am so sorry this has happened to you and I understand how hard it is for users who are new to Airbnb.
There are a few points here I would like to make.
1/.....Did you declare when booking that you had a child who would also be a guest?
2/.....Did the hosts booking page let you book for a child?
Both of these things are important because if the host is aware you have a child and the booking page still allows you to book a child with his/her listing then they have no right to ask you to cancel for an oversight on the hosts part. If the host has set their booking section up correctly the option to book for a child should not be offered.
If you did not declare the child when booking and brought it up in the subsequent message stream with the host, then the responsibility for the cancellation rests with you.
The next thing is, there is a 'free reservation cancellation period' of 48 hours of the booking being accepted by the host. If your booking falls in this category then there is no penalty to you....you can cancel within 48 hours of booking and get a full refund.
- Go to Trips and select the trip you want to cancel
- Click Show more trip plans, then click Show details
- Click Change or cancel
- Click Cancel reservation
Another point to consider is the hosts cancellation policy. If the host has a flexible cancellation policy you can cancel up to 24 hours before the scheduled start of the stay and get a full refund. If the host has a moderate cancellation policy you will not receive a full refund if the stay is cancelled within 5 days of the scheduled start of the stay and if the host has a Strict cancellation policy the host has a right to be paid within 14 days of the stay.
The host is asking you to cancel because if the host cancels a guest reservation they will be penalised by Airbnb. This is one of the reasons the host has thrown the onus of cancellation back on you.
If you are in doubt contact Airbnb service by phone via the help section at the bottom of your message stream with this guest.
All the best, I hope this helps you.
Cheers.........Rob
