ADR strategy for Christmas with littles

I have zero Pandemic DW experience - I’m in need of best advice regarding ADRs and park hopping. We’re there the week leading up to and including Christmas with an 6 & 8 year old in tow. I’m assuming I should err on the side of caution and only book ADRs where I also have a park reservation. Do I need an ADR each day (or multiple) or will mobile ordering be a safe bet if I place the order early enough in the day?

We like having at least 1 ADR per day. I’ve been making them for lunch in the parks we have an APR. it’s a nice respite after morning touring. Yes order earlier than you want to eat when using mobile order.
