There are no way to find a side jobs that you wont sacrificing any , like your time , sleep or energy because my self right now even i do work remotely as well as sidehustle i still don't have time to play on my child and also lack of sleep which you really need to sacrifice those things for you to achieve those things. Lucky those people who can still manage their time but again don't go over it that your health will got affected.
Currently, I have 2 jobs because like many others are saying here, only one source of income isn't enough for the whole household to survive. Yes all of us here in the house are working (but I'm the one who's working from home), but still I prefer having a 2nd source of income just incase my main source of income unfortunately ends up for whatever reason it is.
Like you, I already sacrificed my sleeping time, and there are times where I only sleep 5-6 hours a day because aside from my work, I'm also the one doing the household chores since I'm the only one who's in the house all the time. I wonder how much sleep I can get whenever we will have our own baby. This is also the reason why I'm putting most of my money now in the stock market. I have a specific target where I want to earn X amount of money every month thru dividends. It will be a huge amount for sure, but I know I can reach that. Sacrifice first before comfortability.
Congratulations in advance! For sure, if you are sleeping around 6 hours, it would be cut into 4 hours as you need to wake up to take care of your baby and your partner. A few months after giving birth, it is really hard and there is for sure a lack of sleep, as I've experienced this before, but again, you are happy and you will not feel tired as you will always be motivated. I will be wishing you good health, both mentally and physically, as our work is very draining, and I hope this will be fruitful to us.
