Hi @BeckyCarpenter, welcome to the forum and sorry you are having a problem with your baby monitor charging.
It would be best to get in touch with the product helpline as they are best placed to help you. You can call on: 0800 100 6554 Monday to Friday 9am to 5.30pm and Saturday 9am to 2pm.
If it is out of warranty contact BT's recommended agent on the phone: 0800 980 8999
Cheers
John
