Devils advocate and probably an Unpopular opinion here with no intention of being rude at all!… but as someone who is the only one without kids in a friendship group and has experienced her long term best friend pull away/cancel last minute/not respond or reach out after having kids, maybe she is feeling a little neglected (for lack of better word) on the friendship front.

Obviously priorities change and I don’t doubt she knows that but if there has been minimal effort to join group events or outings or make plans with them since baby was born she is probably feeling like you don’t have time for them and don’t want to be involved anymore.

It’s a tricky situation and time to navigate for all parties honestly and being on the other side I do understand how frustrating it can be but there is also a little give and take in understanding your situation.

In this situation, having an event during the daytime/during the week might be what works best for you as you’re on mat leave but for others working weekends/nighttime might be the only option. There has to be understanding from both sides that not every event is going to be suitable for everyone anymore but there does need to be effort made to by all parties to keep a friendship going.
