I didn't even start climbing umtil after I had kids. put the time in at the begining... let a season or two go with not much climbing. as your children get older you will beable to take more time away. but it is those first cupple of years where your wife will need you the most to be there, to hold her (and to be there for your child) as your entire life changes. let it change. Change with it. work out at home... read al the books you haven't have time to read... do some of those 3 am feedings or at least get up to change the diaper. create the relationship with your child and deepen the realtionship with your partner. If you go on with your life as tho nothing is diffrent after your child is born, even durring the pregnancy she may never be able to forgive you. my .02$
