To ask my friend to come without her baby

[Laptopontable]

I'm currently struggling terribly with depression/anxiety during my third pregnancy. I'm not taking my medication as there are contraindications so as you can imagine I'm not always thinking rationally hence why I'd like an unbiased opinion. I am however seeing all the relevant professionals very regularly.
Anyway, the last week or so has been particularly difficult and I have found myself cutting people out, in particular one of my closest friends. She hasn't really seen me like this before as I'm normally on medication which controls the depression and we weren't as close during my previous pregnancies. I haven't really told her how bad I'm feeling, although she does have some idea that I'm not great at the moment. I really would like to see her, however she will definately bring her 5month old baby with her. For want of a better explanation, I really cannot find the strength to coo and fuss over the baby and really don't want the anxiety afterwards over the guilt that I didn't. I would just like an adult conversation about something other than babies at the moment seeing as my pregnancy is the cause of most of my anxiety.
Does that sound terrible and unreasonable?
How could I ask her to come without him?
Sorry it's long!

I agree with Random Mess' suggestion. How about emphasising that 'child-free' also from your own perspective i.e. you need time away from even your own children? Might soften the request.

I meant from the POV of PP suggesting telling her to suggest a "child free" evening. I don't see the problem at all regarding the OP asking her not to bring the baby; to me that would be clear that the friend needs me rather than just wants a chat. But I would be a bit miffed if the "child free" idea was put forward and I went and the friend's kids were there.

I wouldn't ask anyone to leave their baby to come and see me, but I hated leaving mine at that age and only left them when there was no other option.

Friendship like any other relationship, means sometimes putting the other persons needs first.

In many cases that means the DC are welcome taking into account the fact of lack of childcare/ hating to leave the children etc.

In this case the OP needs support and there are no childcare issues. I'm sure her friend can put her first in this instance.

Could you go to her house? It's likely that, at some point, the baby will sleep. Also she will probably be more relaxed about you not wanting to make a big fuss of the baby.
