Great question!
There are provisions in the child care expenses rules that include your scenario. Because you are unable to care for your child & child care is required for your spouse to work, your child care costs can be claimed.
Usually, child care expenses must be claimed by the lower-earning spouse but because you are on bedrest, the higher-earning spouse will be allowed to claim the deduction if you are on bedrest for two weeks or more. Be sure to keep a note from your doctor ordering bedrest just in case CRA ever wants to see it.
