I can understand her being pissed since it was her custody day, and you decided to tell the kids they could choose who put them to bed. IMHO, the right answers were, "It's up to Mom tonight." or "Mom looks excited."

Not sure we should be buying things "together" post filing.

It's true, that introduces complications. A simple side-step, if you feel you two are amicable enough to work together at least for now, is for her to buy an iPad for one kid and you buy an identical one for the other kid. That reduces costs, but still provides clear ownership in case there are more disputes down the line.
