Ah, all good replies to my ears. I have two young 'uns – nearly 4 and 1.5 and my cycling life has changed dramatically from being a pretty reasonable racer, both road and mtb, road trips all over the place, and regular long w/e runs. To echo all the above; now mainly a solitary rider, squeeze rides in whenever – and always be ready – no faffing! I was quite wound up, immature, selfish about "my" lack of cycling, regardless of how my missus felt.
Now I just go with the flow, enjoy the fact that the older boy rides his wee Islabike really well and they're great wee people to bring up and later enjoy outdoor activities together.
Oh, and to get rid of my lack of competition angst, I am now training for my local half marathon, which only takes 5 hrs a week as opposed to 12ish for bke racing.
MTFU, kids are for life not just for Christmas!
