@ Confused,
Pardon me if I'm crude in any part of this passage.
Your mum knows that you are pregnant?
You need to consider the expenses required for the baby and yourself before all other luxury expenses, and judging by your monthly wages, you will need to be very disciplined in saving up for the neccessities which includes but not limited to, delivery fees, milk powder, diapers, checkups and jabs for the infant, doc visit when baby is sick, your own meals and transport.
The above are the more immediate ones, but in the long run, there're child's education, more of your own neccessary expenses like paying utility bills, S&C charges when you have your own house, setting aside expenses for your own medical needs etc.
The need for money gets bigger along the way, unless your mummy can afford to cover the shortfall, you will need to fork out most of the expenses by yourself since you are the immediate parent to your child. Don't forget that your mum needs to take care of her own future medical and retirement needs as well because if she isn't properly prepared, that medical burden or finances shortfall will eventually fall back onto you.
I used to set aside S$1K (food, baby's insurance, savings all in) every month for initial baby needs right from months before my daughter was born. Luckily she's healthy, but... she has a huge appetite. Formula milk can cost you 70-80+ for a big tin but probably last you as little as 3 weeks depending on your baby's appetite. If you can produce more than enough BM for a long time to come, the milk issue is resolved until probably the baby turns 9mths or even up to 1yr old, that's a big IF. Jabs and doc visits are the most costly I would say.
Once baby is borned, make full use of the CDA acct given to every newborn, save 6K in it and govt will give you another 6K, this should nicely prepare you for the baby's initial years' needs. You might also have the baby bonus of 4K given to you by the govt in installments, use that money as your CDA savings for your child, don't spend it unnecessarily, the CDA acct will be a life saver thou it won't last forever.
But being a single mum, there might be limitations as to what you can get from the govt's proposed benefits. You might want to engage your GRC MP's help if you met up with rejections.
All may seem harsh and impossible to go thru, but I always believe that with a will to survive, you will be reshaped to adapt to the impossible and probably even excel.
Do bear in mind that alot of responsibilities and sacrifices come with parenthood, you need to be prepared for that before coming to your finances. A child needs alot of care and attention from his/her parent, neglect them and you may find problems trying to even communicate with him/her in the near future. That may means sacrificing a significant portion of your own private times. Sacrificing your luxurious needs. Significantly increase your tolerance towards all the baby cries, mischiefs and need for attention just to name a few. In short, you must love the baby unconditionally as the baby is innocent.
If you are more than convinced that you cannot achieve mentally, physically to be a parent(Financial is never the biggest problem, just live within your limits.), then consider forfeiting a life as your last resort.
