I have both.

For me, my contract is terms of service. What hour care available, what fee is, when fee due, start date of child, day registered, my name, parent name, who care provided for (child name), closure day, statement fees due regardless of attending for days reserved, which day each week reserved. Basically my agreement with that client. This might change based on client.

My handbook is more generic. It my polices for all client and not change. Sick policy, late payment fee, late collect fee, vacation policy for client and me, toilet train requirement. Notice period for my vacation, notice period to terminate care both me and client, process for short notice closure like own sickness or serious storm or no power, vaccination policy. Notice period for change in fees too.

Because these two different document, in contact I have statement that parent seen handbook and have copy and understand that policy is part of contract and if signing they accept all policy. Also have statement in handbook that policies are part of contract.
