I have 3 kids and love being a father. Yes it is very hard work, very expensive, tiring but it is incredibly rewarding (emotionally). I would have more if my wife would agree!
Seeing my son's face as he stood on the podium at his recent gymnastics competition after working so hard at it, seeing my daughter win her medal at a tetrathlon on the umpteenth attempt, watching my youngest develop at school and learning to read. All priceless moments which make you so proud to be a dad. Really proud - so proud you want to tell everyone (even on a forum of people you don't really know!) It is a very special feeling, that I don't think any amount of free time / disposable income can replicate.
A lot of my friends don't have kids and have more free time to pursue hobbies, which I have long forgotten, have more disposable income to enjoy on themselves, have nights out on a whim. Do I complain - no way. Would I swap - not a chance.
But do I recommend to them that they should really be starting a family - no of course not. They see the fun we have as a family, they see the rewards we get as being parents, they also see me running around here, there and everywhere and hear the arguments! Everyone is free to make their own choices.
For me - I don't regret it one bit!
Silver 156 GTA SW, Q2, Koni FSD's, Eibach springs and anti-roll bars, CDA induction, re-map, Wizard/Pud exhaust - fantastic!
