I missed out on lots of fun things when my bub was a newborn because I listened to people saying "your life will be mainly around home" "you have to stick to a routine - cos babies like routine and if you dont you will pay for it!!" etc. I was so freaking bored being home all the time with my newborn trying to enforce a routine. Finally I popped her in the car and drove to the shops etc and you know what - it didnt matter. she still did the whole feed/play/feed/sleep thing and I wasnt bored anymore.
I restarted my life - coffee with the girls, morning teas at work, mothers group, playgroup, etc. Yes my life was different in the activities I did - coffee vs wine bars, playgroup/mothers group vs clubbing but essentially my life went back to normal. It was social again.
I agree with Girl X in that if you want certain things in your life you have them even with children. We love to travel but as we are on one income - we only go overseas ever two years but locally at least every year. But as decemberbubba said - things in life do change with children but its up to you how much you change it.
I still catch up with the girls but now we meet at a park so we can chat and sip coffee whilst I watch DD play. Cafes dont work anymore with a toddler and naptimes are precious (I sleep too!)
Dinners or late nights only can happen once a week as it stuffs up her sleep too much otherwise for the rest of the week.
My life did change cos I had to make new friends that were 'mummy' friends. I still have my tight knit circle of friends but less of the ones I just used to hang out with.
My day has changed to starting every day by 5.30am and bedtime by 9pm. But I do not resent it at all. I am much more productive now than I ever was pre-baby.
I do wish tho that I did more with my newborn. newborns and babies <7/8mths are infinitely more transportable and accomodating than toddlers.
