Anecdotally, when my work schedule was wonky for a while I would do the same with my kids. Those few extra minutes hanging out with them in the morning were something I valued a lot. We got to talk and relax a little bit after the rush of getting ready in the morning. They had all day to spend with their classmates so a few extra minutes in the morning wasn’t going to change much.
A suggestion: If you want to make friends with other parents, morning drop off is the worst time to do it because everyone is going from the rush of morning routines and mentally preparing for their jobs. After school is better, but the best is at events and activities away from school hours completely. Our schools have done parent socials that have been great for meeting people. Sports and activities are also a great way to get introduced to other families.
It also helps to be the one leading the charge. We’ll do things like go to the museum or other activities and then send invites to 5+ other families. Tell them to invite other families.
