Whether to take full time job with toddler

[Imtootired]

I have an 11 year old and an 18 month old. Before I had the little one I was working part time in a supermarket and studying. I finished my arts degree before he was born and took the maximum two years off work to spend time with him and do more study and search for a better paying job. I’ve been applying for government jobs with part time options but haven’t had much luck. I am in Australia and get government payments and all my leave from my job spread out over the period. I had a phone interview for a job I applied for yesterday working customer service on the phone for a gov department. It sounds ok but probably would by quite boring. It’s 63 000 p/a so much more than my other job but only a 6 month contract with possible extension or permanency. In Australia there is a new scheme where the government will guarantee the deposit for home loans and I really want to do that because rent is ridiculous where I live and a mortgage would be almost the same money and we could have a bigger place and security. I’m wondering if I get offered the job if I should take it to try to get into the housing market. I really wanted to have one or two days during the week with my little one for play group and swimming lessons. Also my older son is starting high school next year and I really want to be there for him to start him in a good routine and make sure he’s starting out on the right foot. Things are crazy in my house as it is trying to stay on top of the mess and bedtimes. I don’t know how we will cope rushing in the mornings and everyone overtired in the evenings. I’m a single parent. I know some people have no choice so I’m very lucky. I’m just not sure if I would be taking on too much going full time and if it would be the right thing for my kids. If I go back to work in the supermarket I would have less money but more flexibility and we could still get by with government payments but might not be able to get a home loan or only the smallest available and I really need a backyard for two energetic boys. If I go back to my old job I can keep applying for more part time gov jobs. I’m 34 and I really want to start thinking about the future but I don’t want to miss out on such important times in my kids lives. Please I really need advice

Sorry for the wall of text. Forgot to say that my little one already goes to daycare twice a week and loves it but is tired after. I don’t think there will be after school care for my oldest next year when he’s in high school. My mum can help a bit but I don’t want to ask her to get him all the time and I’ll feel bad if he comes home to an empty house

Sorry for triple posting. I’ll just make a tldr: if you were a single parent with an 11yo and a toddler would you work full time for financial benefit long term or spend more time with your kids and just get by ok?

I’d take the job. I say that as a single mum of a 2 year old. It’s worth it.

I think full time jobs are actually easier during nursery years than when they have just started school. Unless you're willing to be part time for 5+ years id do it.

Thanks for the responses. It would be really good for us and it would be ok but it’s also my older son and making sure he is organised and doing his homework etc. Luckily I’ve still got time to decide
