Loss of confidence after maternity leave

[Purplelemon7]

I’ve read a lot of posts on here about women struggling with leaving children in childcare - thankfully I have great childcare and my children have settled really well.

I’m really struggling with my confidence though. I had two back to back maternity leaves and I feel like my brain isn’t working. Especially worried about leading meetings with clients. For context I work in a mid level management role in consulting. Most of my team members left over the last two years so I effectively have a new team who don’t know me and I worry that they will think I’m incompetent. It’s stressing me out constantly and I can’t switch off. I try to tell myself it’s just a job but I find it really hard to have perspective. Would love to hear about others experiences and advice

I raised quitting in the context of work life balance not suiting me at the moment. I said I'm thinking of quitting or finding a part time job.
This has opened up a discussion at least on how they might fit me in part time but it's tricky cos where they want me to sit in the structure doesn't lend itself to part time. I've decided that's their issue though , I'm trying to relax and see how it plays out.
I'm lucky in that I have some money coming to me in August so I genuinely will be able to just quit , it's given me some extra confidence for negotiation.
My brain has genuinely improved in the last few months though. I'm not perfect at all but definitely less unsure of myself.
