its hard to tell you because everyones circumstances are so different.

If you call c'link and ask them, they'll be able to tell you exactly how much ftb you'll recieve based on the income you'll recieve and your partners income.

Obviously working will make you better off and FDC is roughly about $5 per hour. So if your hourly rate is going to be only $5 or $10 per hour, it probably wont be worth the effort iykwim. Take your CCB into account and you could only be paying $3 per hour for fdc.

I work 15hours pwk and have my little one in fdc for a total of 18hrs pw and i pay $77 per week. ( i get 30% back from ccb) So my income does make us better off for sure.
