Very random OP but are you half decent at taking pictures?
A friend of my seemed good using iPhone Portrait mode, and got herself a professional camera. She is no pro but does take lovely photos and is good with kids - She charged £180 for a 30 minute family shoot! £250 for a newborn shoot. £550 for a 3 hour 'Outdoors' shoot
She's been going a year. And it's helped her massively. The initial cost was her £300 camera. Happy to link you to the one I'm talking about via Amazon etc
It's really hard. Especially without a partner. You're paying childcare costs, providing a home for them and paying for all bills and outgoings on one salary, without financial assistance
This means you either need to be able to work to something higher up quickly (hardly going to get the rewards for it if it's taking years and years), or change professions. But again, this isn't always practical.
In addition to that, I wish posters would understand you can't just take a DC and run off somewhere further away
The courts can order the child to be close by, within x amount of miles. And that's without considering them implementing other measures such as more legally enforced time with the dad. It's all very complex
Of course, as a single parent you also need your family and friends. You cannot just be expected to uproot like that. How ridiculous.
