@Redrosesblue I really feel for you.
I’m self employed and me and DH had a serious chat about this before we started TTC. My “old” business was a bit like his - not in industry, but in that I was always working, but pay was sporadic, and averaged £1750 a month, which isn’t great. The sporadic nature meant we weren’t comfortable relying on that money, and if we didn’t include it, we couldn’t afford to TTC.
I think DH needs to look at that, whatever you decide here. I don’t say that lightly. My business is very much a part of me, I sobbed at the idea of giving it up. In the end, I took on some part time evening work, which meant I had less time to do in the job and had to prioritise the better paying, faster paid stuff; and gave myself six months to sort it out and find a business model that was more compatible with life. He’d need to do that if he wasn’t with you... we agreed I’d look for work if things weren’t looking up by month 4/5. We didn’t need to. I wasn’t wasting time before, or not putting my all in, but nothing focuses the mind like knowing this is it.
It’s absolutely your choice what you do, but I’d want to know DH was doing more than he is. He has to carry more of the financial load, especially if he’s keen for the second child.
I have a friend who has a tree surgeon partner, he’s been working as that three days, and with companies for the other two - one doing relevant work; one driving for a builders. It means he’s firmer with when people want to collect, people book more in advance and pay a deposit as they want his time and it’s limited, and if he does have a bad week with late payers, he’s got two days a week of other work that he’ll be paid for. That’s covered childcare for their two little ones. He started off in a local shop, before he found the work he preferred, and they paid him to stack shelves - he got a set amount, so if he worked hard, it didn’t take him hours - and deliver things for them if he needed extra work. He’s expecting to be able to stop the extra jobs in June, when their eldest is at school full time.
It’s not saying he can’t have his business... but he needs to make it into a business that can support his family now, like I did, or he needs to do extra work until it does.
