Going back to work - Will i regret not being a SAHM?

I'm due to return to work in a couple of months (my LO will be 11 months old). I'm a nurse who will return to doing 0.8 shifts/fortnight, and my husband does 4 days on 4 days off 12 hour morning shifts.

Being raised by a full-time stay-at-home mum, along with my three brothers, I feel like it definitely shaped who we are today.

In some ways, there is guilt with going back to work, and knowing that i wont be able to give my 100% attentjon to my son as he grows up, same as how our parents raised us (with one staying at home).

But also, as much as I'd love to be a sahm, our finances doesnt support me being a SAHM :(

Idk what im looking for, but i guess just thoughts on this, if youre working - how do u make it work, do you think i should cut down on hours so i can stay at home more?
