Moved from 70/30 to 50/50 - my kids are handling the transition better than I expected

Honestly thought going from mostly my house to true 50/50 would be rough on my 6 and 11 year olds. But having a predictable schedule (alternating weeks) seems to have actually helped them feel more settled? My youngest stopped having the Sunday night stomach aches he used to get. Not sure if that's correlation or causation but I'm not questioning it lol.
