Housewives Investing: Which Brokerage Platform Offers the Easiest Start in Singapore?

Looking to start.

Hubby will take care of most of the expenses and give me about 3k for personal expenses + miscellaneous for the baby.

A lot of stories here is based on working adults. I just want to explore if there is a housewives edition to investing and what investing opportunities there are for me as a housewife with a 3-month-old baby. i am 40/F and currently have no debts other than just mortgage.

As a housewife, a bit paiseh to keep asking for money. I have my own savings but thats more for rainy day funds. Am i correct to think of investing using brokerage platforms?
