How long would you live with a kitchen like this?

Time to call in the professionals.

Our next door neighbour hasn't had a kitchen since September 2020,he's got a microwave in the living room and he eats a LOT of pizzas.

We survived with a slow cooked, micro, electric kettle and mini fridge on a table while our kitchen was done for about 6 weeks. Washing up in the bathroom sink was the hardest part. We had no DC then and it was miserable enough.
You need to put your foot down with your DH to prioritise finishing your kitchen.

Just buy in help or get ready-made units that fit in with whatever he has done. You said you can afford it and he is taking the piss both on the length of the job and making you be a lone parent. Seems like he would rather stretch out the DIY than do any parenting.

I lived like that for 3 months when pregnant. Would absolutely not agree to it continuing unless unavoidable once baby arrived, and especially with bottle feeding and needing surfaces. It's not unavoidable in your case as you can afford to buy in help!
I'd also be furious with DH for not giving me a break at weekends from parenting, or indeed just actually wanting to spend time with his child. Change this asap OP otherwise he'll lack confidence dealing with the baby, say they prefer you, have to ask you how to make a bottle, not notice nappy needs changing etc, and this will be the status quo for the child's whole life, with mum as default parent.

We had our kitchen ripped out when our baby was about 5 weeks old, but finished when she was about 10 weeks, and that was long enough (and we stayed with my parents!) solidarity though, my husband did a lot of DIY so the full week of mat leave and then a full weekend also solo childcare is super hard work

I’d be ok with the kitchen for a few months.

I’d be ok with the slow-progress-non-helping DH for about 20 minutes.

Last time it was 5 weeks and I almost went over the edge.

Renovation was late starting, took about 6 months, I was pregnant, I came out of hospital to no kitchen, we had a stand pipe in the kitchen, kitchen never got its snagging done, as I just wanted all trades out so I could enjoy what was left of my maternity leave. Luckily I was able to breastfeed.

Have done it for a couple of months pre dc - moved into an old house with nothing but the sink - and currently have no oven, but do have worktops etc so can't complain.

Two things jump out at me - your DH is barely at home compared to you, so the impact on him is minimal whereas this is where you are 'stuck' every day, along with a baby. Secondly, you say you do have the money to finish off but 'DH not keen to spend it'. Taking my 1st point into consideration, sod that frankly. He's essentially telling you to put up and shut up, while he's out of it every day. That's not being a good husband and father tbh. If the money is there, it needs spending to give you & dc a better home.

We lived similarly for about a month and I wanted to either kill or be killed by the time we were done.

I would be having a conversation with DH - either he takes 2 weeks off and you get it done, or you get outside help in. I would give a time limit for the two weeks off as well, and I don't care if that's unfair because it's summer holidays, it is supremely unfair that you are having to live like this with a small baby.

Why is your dh not keen? It’s this kind of shit that led to my separation to be honest @Pinkstuffs. His constant need to prioritise his wants/desires to do things his way before the families needs.

I coped for about 6mths, with a young baby and I was doing the kitchen fitting myself. Breastfed not bottle fed thankfully, as at that point washing and sterilising might have been the thing that tipped me totally over the edge.

If you can afford it I'd be saying enough is enough. I can't stand living upside down like that

With a small baby? I'd have no patience past about 2 weeks!

We did it for 10 months. It almost broke me. Cooking, storage and washing up on the dining table. Having to schlep to the laundrette every week.

I would never, ever do it again.

But it has been worth it as I love my new, spacious kitchen.

I can't understand why anyone would live like this for over 10 months when they can afford to get someone in. You should be enjoying your first year as a family and you should be a team in looking after the baby, you must be exhausted doing it alone 24/7. Even more so not having everything you need

We did it about 18 months. No roof for a winter. No heating. Child was 5/6yrs so not the bottle feeding issue. It was absolutely soul destroying and I will not for one second take for granted hit clean running water and a roof over our heads.

Why is it taking so long? We've always fitted our kitchens ourselves, always within a couple of weeks. You need to get DH to work out a proper timetable, or else accept, with good grace, the help of a builder.

As someone who was promised if we bought this house it would have a speedy renovation , have now lived in a building site for 12 years , you have my sympathy !

We had no kitchen at all when I was pregnant about 5 months to 8 months. We just had a table, microwave, fridge in the lounge and washed plates in the bathroom sink. It was OK I just lived off ready meals and school dinners at work :)

Just need to make another 'kitchen' somewhere else!

We started exactly this when our baby was 6 months and it's still the same a year on. Hoping to be finished by Xmas

We had major works done and it meant no kitchen for 2 weeeks. We had a temp set up in another room, but it was hard! I don’t even cook (my husband does it all) but found it unbearable. The lack of a dishwasher was the hardest.

With a baby, not at all.

8 - 12 weeks max. Given that you can afford it and are fed up with it you sound like you really do need outside help.
