OH and I lived together at his parents house for 6 months in Nova Scotia then decided to move to Ontario (where I'm from) and moved into my parents house for 6 months. My parents bought a duplex to rent out and ended up renting the top to OH and I and the bottom to my brother, his girlfriend, and her daughter.
I couldn't handle living at either parents house. You don't feel you have a say in anything when it's not your parents and OH would get frusterated with my parents (and hide it really well until we were alone, thank god) and it was stressful on our relationship.
I love being on our own but the bills are really hard. We both work full time jobs, mine paying about minimum wage and his paying 50% more than mine and we live paycheque to paycheque, it's really hard to save any money for when LO is here. There are so many bills you have to think about. Both your cell phones (if you have them, I just got rid of mine and instead got a home phone) cable, internet, car payments, car insurance, visa payment, groceries, gas ect. Luckily heat water and electricity are included in our rent otherwise we wouldn't be able to afford it. We don't live badly, we always have everything we need, we just don't often have much left come our next paychecks unfortunately and there isn't much to go out and have fun with.
Then when I'm on Mat leave I only make 55% of what I'm making now. I'm doing a mortgages course because my dad is a mortgage broker and said I could do a couple of deals a month for him and he'll pay me to help supplement the bills so hopefully that will help. My advice would be to stay with your parents for maybe the first year, if they're there to help with childcare you could get a part time job and save half of every paycheck, that way you have some money saved up because moving in general is expensive. You always think you can get a lot of hand me downs ect but then theres things you realise you need that you didnt think of. Kettle, toaster, microwave, cutlery, cooking materials ect ect ect ect ect. Plus you'll want to be sure that even with moving out your LO has everything they will need. You'll have a better idea of what this will include after experiencing it for a little while.
I know the idea isn`t exactly the best but I`m just saying its hard living on your own let alone with a newborn. Good luck!!! xo
