Not easy trying to balance things but you are young you still need time to enjoy life as you cant turn the clock back
I am on my own but still have to give up thing ( dont have a tv only have the phone I have due to being my son old 1 ) both my kids have left home btw they are a little older than you 1 has a 1yr old daughter her 2nd due late dec/early jan her partner is a van driver on a low wage ( yep they get tax credit not a lot but it does help ) of course us parents help out as much as we can
You need o sit down work out your finances see what you can cut back on a little as money is not everything time with family is more important dont be like a lot of us & have a relationship break down if you can work sun -thur when you off have time together make time when you home at night eat together no tv on sit & talk
Although my last relationship broke down partly due to my job ( he was also a driver ) we did make time for each other mainly on a sun mor when we were both off ok you have a young child why dont you get up with her 1 mor when you off let your wife have a lie in take her a cuppa / breakfast in bed that mor whn daughter has gone to bed make some time for each other at least 1 night per week
When you both off during week go out do something as a family ie go to park sea life canter or other museum most are free now
