Think it depends on your friend. Is she sad not to be invited over as she would like to get out, with the baby? Or does she in fact prefer it at her house? I think you should have a conversation with her and say "Hey, we want to see you! We don't want to put you out by expecting you to cook for us coming to yours. But also we don't want baby to eat stuff off our floor because we're not very child proof. What's the best option for you- come to ours and be on baby focus all the time, or we come to you, and we can bring a home cooked dinner? Also, are you upset we havent been asking you over? I get the vibe we aren't doing the right thing for you. Tell me what you need at this stage of your life, because we haven't known what to do for the best."
That would be easy to bottom out.
The problem is, your post is all full of resentment- you want "your go" at having social occasions,the way you want them, at your house, without having to make any baby accommodations. The way you snidely say "they were very keen on everyone coming to theirs the first few months" as though you're all dancing to their tune. Which is such rubbish, as anyone who has a newborn knows.
Look - whether you choose to not have kids or can't have them, the fact remains if a person has no significant caring responsibilities beyond themselves, the amount of leisure time, and fun time, and discretionary time they have is infinitely more than someone who has kids. That's just the truth of it. And it's why child free people whinging about accommodating children always sounds so petty and selfish. You have simply no conception of how much free time you have in real terms. So why is sorting your house "For 2-3 hours" such a big fat deal?
I also think guests come, and they should be welcomed if you want them to come. I think you should be pleased to tidy up your house for your friend. Move a few bits, put some towels and a bin on the bathroom floor for a changing space, maybe push the boat our and buy a packet of wet wipes. You've probably got a bedroom or spare room the precious ornaments could go in.
Can you not see it as showing how you love your friend and want her to be welcome? If someone was staying over, you wouldn't huff and puff and roll your eyes at putting flowers and clean towels in the guest bedroom or changing the sheets to the nice matching ones. You'd do it, in a happy glow of feeling like a lovely host. Why can't you change your house to accommodate one baby, for one day?
