I started a Google sheet I am filling in to list difficulty and baby count: https://docs.google.com/spreadsheets/d/1xDOWtsF8bwFKgHrP16YEYM0vUrfXw50uMGnQ1SAbiJc

If you want to contribute, just fill out the form: https://docs.google.com/forms/d/e/1FAIpQLSfeCmLlHQ81CdsSn4DLfHESK3oHIonqKWBwgmIsH-8oi4_wUA/viewform

I'm hoping to crowd source this data to fill it in. Thanks!
