How to deal with this mum?

[BobbyDazzler11]

NC as possibly outing.
I have a baby who is almost one. We don't have any family nearby and I am still off work.
We love getting out and about every morning then coming back in the afternoon for long nap and chill time for me (bliss!) also clean up and start dinner. Baby and I , have a fun weekly routine of activities (mostly free!!) inc library class, and a mums walking group.

I have a neighbour with a similar aged child. We spoke a couple of times pre-baby about the usual neighbourly things, bins etc haha.

When the babies came, she was always saying we needed to organise to do stuff together but never actually took initiative to organise it. I asked her for a few walks which we went on. She is quite strongly opinionated and also very negative which I found quite tough. She was very fussy about where we walk and made clear doesn't want to go for coffee or any local attractions , fine. Everyone is different.

I shared with the activities we do , encouraged her to get involved and she now attends most weeks.
However.....All she does is dig at me (to me and the other mums!) how I need to make more effort to do stuff with just her ??
She is constantly saying it every single time and that it's ridiculous we don't do enough?! (Again, no actual initiative to properly ask me to do something on x day or x time, just says it needs to be sorted!)

To be honest, I am getting sick of it. I really enjoyed these activities and I feel I am spending enough time with her in these group setting. But every time I now have to hear her saying to everyone how I don't make enough effort and coming up to me singularly telling me I need to do more with her as our babies will be in the same school and year for future.

We were never friends before and to be honest, I don't want more than what we have now. One comment specifically is that I need to come round for a cup of tea in the afternoons and it's ridiculous I'm so close and 'don't bother'
How do I handle this because the comments seem to be getting worse and even more frequent?

Is it a dig or just a suggestion?

Handle it by being honest.
"you haven't actually invited me though have you"
" It sounds like you need to get out there and make some more friends"
"Why do you keep saying I need to do more but you don't arrange anything?"

Then if she does invite you be honest..."I can't in the afternoon as that's when baby naps and I get dinner ready."

@Choosingmiddleschool at first I'd thought that but it's constantly. To every single person in the group every single week!

As soon as someone says 'oh your neighbours' she will jump in how yes but I make no effort it's ridiculous etc etc

I suppose it's tough because I don't actually want to. I am happy to keep it in these group settings and that's enough.

But I want the comments at the groups to stop!

"I've had enough of comments like that, thank you." And then change the subject.

Or

"haven't you got other things to do? In the afternoon I have nap time and then get dinner ready, I have a routine that works for me. You seem like you haven't got enough to do ....have you been to XYZ?"

I think you just have to respond to what she's saying. It seems like you're feeling really uncomfortable when she says it and then go quiet in the moment. So have a think about what to say and be prepared to say it despite feeling uncomfortable.

@OilLamp that's a good idea thanks!!
