Communication style differences are driving me nuts

My ex is like... she wants to discuss EVERYTHING via family meetings now. Kid needs new shoes? Family meeting. Summer camp options? Family meeting. I just want to text 'hey I'm buying him Nikes, sizes 6' and be done. But she's always like 'we should discuss this as a co-parenting team.' And yeah I get it, unified front and all that, but sometimes I feel infantilized? Like I should be able to make decisions about the kid during my time without checking in. How do other people navigate this without being difficult about it?
