Kit will automatically select your plan depending on the number of children you have profiles for in the Kit app. When changing plans, Kit will calculate the new fees and provide refunds, if applicable. If you are on a free Kit membership, the updated fees will be reflected on your first charge after the free membership period has ended.
Changing to a multi-child plan
To go on the multi-child plan, simply add another Kid Profile in the Kit app.
Changing to a single child plan
If you have multiple children on Kit and decide to go on the single child plan, delete your Kid Profiles except for the Kid Profile you wanted to keep. Your plan will be automatically downgraded to a single child plan.
Deleting a Kid Profile is permanent and cannot be recovered.
