To insist DP goes back to the office

Yanbu

You can't raise a baby for weeks on end in one room - that's just shit for you and them

If he’s reluctant to go back to the office why not stop being a lazy arse and move his work station upstairs, I’m sure it wouldn’t take long, but then again it’ll be good to get him out the house 😊
Sitting in the bedroom with your baby whilst he roars on a phone, I think not.

Working from home isn't about you though is it. It's about staying away from people and not catching C19. We've had 3 people in our place of work die from C19. Id prefer to work from home and piss my partner off rather than gambling with my health.

I can understand how you feel. I was ready to kill my partner by the end of his three weeks paternity leave and we weren't even in lockdown.

I love my DH but I can’t wait fir him to return to the office.

Do you only have one bedroom?

In lockdown I had a table in my not-large bedroom. My loud toddler grandson would have made it impossible for me to work downstairs.

Of course he can work upstairs, although will that make it too noisy for your baby to sleep up there?

If he can't go back to the office, why don't you set the table up, upstairs for him?

He needs to move upstairs.

As an aside, I was discussing with the currant Mr jam (see what I did there 😉) and we both wondered with the likelihood of more and more people working from home, would the fashion for open plan living be reversed?

Seen your update.

He needs to go to the office.

Sort out an office space upstairs for him if he refuses to do it himself. He should be bloody grateful he has the option to work safely at home and should be making it work for everyone not just himself.

Perhaps offer him a choice?
Go back to the office
Work from upstairs
Work from the dining table but you will not tiptoe round him. if the baby cries, you won't be leaving the room. You won't live in silence. You will watch TV , etc, because you cannot live in one room, worried about making the slightest noise.

Spend all day downstairs and make a lot of noise.

I feel your pain OP.
My DH is working from home. He has an office he can use out of the house and a home office. But instead he's working from our kitchen diner and living room. He paces around the the house shouting down the phone (he's annoyingly loud) all day. I have no space or peace. He also asks me what I'm doing constantly. It's driving me insane.
Stick to your guns for your own sake.

Buy him an early xmas present of a desk and evict him upstairs

I agree with this.

My husband's one day a week in the office coinciding with my day off was the best thing for my mental health. Since March I'm furloughed and he's only left the house for medical appointments with me driving him.
There is no other room he can work in so we share the living space. Him working, me doing chores, watching TV etc etc.

At first I crept around but now I don't care. The only thing I don't do is vacuum while he's working. And I wear headphones for TV.
It's my house too.

He's being immensely lazy by not sorting out a desk space upstairs. I'm not sure how long his commute is but in the time a few commutes would take he could have sorted working space upstairs.

Why would you feel bad? He can’t be arsed moving upstairs so it’s back to the office for him. Tell him if you change your mind about basing work upstairs you can work from home of course but I was going insane with having you home all day using the one main area and making that bloody phone call. Having your first baby is not that easy either!

Would a compromise be possible with him working in the office, say 3 days a week? Then you could spend one day at your Mum's and put up with him one day a week.

Or he gets a desk and works from upstairs.

YANBU to need the downstairs for you and baby during the daytimes.

I think YABU personally although granted there is some compromising to do - either convert a spare room or do a couple of days in the office.
I don't see why he should commute in there 5 days a week

So have you given him the option of moving upstairs or just said it's the office or nothing? If he would genuinely rather an awkward commute and sit in an office all day on his own over just moving upstairs, I suspect there is something you're not aware of in terms of the practicalities of working upstairs.

He's already said you don't have to tiptoe around him so I don't know why other posters are suggesting you make lots of noise. You're the one creating the issue of staying with the baby in the bedroom, your partner has told you to use the house as you normally would.
