There are just too many unknown variables for anyone to make an informed comment about OP's situation, so the posters on the thread can only guess at the situation and use their own experience to inform their views.
For example:
Is the loss of DW's income going to stretch the household budget to breaking point or is it just a dip in the overall finances?
How much disposable income is there in the family finances? Does paying for a cleaner mean cutting back on food, or a holiday to Florida? Is the consideration of cutting back on the cleaner because it is genuinely going to stretch finances to breaking point, or is it because the OP thinks his DW will be lazing about the house anyway, and she should therefore be doing it? (and tbh, that was how I interpreted the tone of the first post)
Are there other 'luxuries' that are also being considered as part of the adjustment in finances? Phones on contract, holidays, gym membership, expensive hobbies?
What savings are there to cover for this scenario?
What are both attitudes to cleanliness and tidiness of the home? Is it a big deal if floors aren't mopped or hoovered? (personally I have quite a low tolerance for chaos, so would find it quite challenging not to have the place clean & tidy)
How much does OP already contribute to cleaning and running of the house, and how much does he intend to do after his DW gives birth (and not just in the first few weeks)?
OP and his DW can't even know what sort of temperament and needs their baby is going to have. Similarly, there are a lot of unknowns around how the DW is going to cope physically and emotionally following the birth.
And OP, I honestly don't see the replies and opinions on here being evidence that misandry is alive and well amongst a bunch of feminazis. Your posts do show a certain attitude towards your DW and posters who have taken the time to reply. I don't have time to cut & paste everything, but a few examples, along with my thoughts:
Wow ladies, the powers of presumption are strong here!! - honestly, referring to a group of posters as ladies is patronising. As I've said above, posters can only reply on the basis of the information which is provided and their own experiences. Comments about the powers of presumption just make you sound sarcastic.
so I don’t need a lecture please 😊 - people weren't lecturing, they were providing opinions, which you asked for. Just because they were opinions that you don't agree with, doesn't make it lecturing - but it does give a very clear message about your attitude towards others if they hold a different viewpoint.
Yes, I had considered keeping the cleaner for the first month or two, to at least give her a fighting chance of recovering from childbirth - this statement makes it look as if you believe that this decision is entirely yours to make. This may not be the case, as you stated later, but I know I certainly picked up on it when I read this statement. Your comment about 'giving your wife a fighting chance to recover' also sounds patronising, and again reinforces the impression that this is a favour you are bestowing on her.
Since you both rather pedantically picked up on my use of “I” rather than “we”, the “I” in this statement was in reference to myself as it was I doing the thinking. as above, I don't think it was pedantic of posters to point out your statement. A person's use of language belies their fundamental attitudes and beliefs.
But I’ve threatened that with the next baby, she can go back after 2 weeks and i’ll have the 9mths paternity. I know you said this was a joke, but a lot of truth around attitudes are conveyed in 'jokes'. This suggests that you think maternity leave is a piece of piss with your DW lazing about doing nothing, or at least having the capacity to do what the cleaners is currently doing.
Silverbitchtree - I’m not sure what powers of inference you possess, but they seem to be malfunctioning slightly. Again this just reads as sarcastically having a go at posters who hold different opinions to you.
I think I will delay the cessation of the cleaner for a month or two into mat leave. That old 'I' chestnut again.
Ok, to put some of the harmful misconceptions and presumptions to bed As I've already mentioned above, without full information people can only respond on the information which is there and their own experiences. It doesn't make them misconceptions, and they certainly aren't harmful. I'm not sure why you chose to characterise people's comments in that way. Adding another 2 children into the mix late into the thread is a bit of a massive drip feed.
There seems to be an immense amount of hatred towards men in general, principally due to bitterness regarding biology and the fact men don’t have to carry young, or so it seems. This, coupled with a lack of sense of humour, means that you come across as a bunch of jumped up, judgemental bigots, who only serve to give genuine feminists a bad name. Where do I start?
I'm not pointing these out to have a go at you OP, but you seem to genuinely not understand why you may have got some of the responses you have, resulting in you calling posters on this thread a 'bunch of jumped up, judgemental bigots'. If it suits your internal narrative to think that you are getting a hard time because you are a man then I very much doubt that anyone will be able to change that. However I have seen a great many threads where male posters have been provided with support and good advice, so I'm not sure I agree with your viewpoint.
Whatever you and your DW decide to do as a family, I hope you all have good luck with the baby. When is it due?
