You're in for a surprise by the sound of it! Assuming you are not going to leave it all to the mother or subcontract out the baby, both popular but caddish choices, you will notice a certain lack of sleep for a while and then difficulty in moving about due to huge heaps of pampers and soup cooking... climbing will be the least of your worries!
Having said that it eases off after a bit and it's true that it does kids no harm to be taken out even very young, they like camping if it's not too cold... one point to avoid is taking them out for long days in baby-rucksack things in the freezing cold... you will be warm enough but the baby will be slowly turning blue as he or she isn't getting any exercise... it might seem obvious but I've seen it done on several occasions.
I have know couples that broke up because the bloke (it's usually this way round) insisted on going off climbing and leaving the mum at home with kiddy... after a bit she got fed up... alternating outings is better. This can lead to a problem if mum doesn't want to go out but resents dad doing it... tricky, and quite common (from experience).
Last point; the first one is always the one that marks you the most as it's all new... bringing up a baby from birth is in fact quite an interesting experience (I wouldn't rate it on the blissful spiritual level that some do though, but it is quite interesting) and one worth doing fully... once it's over it can't happen again (for you, that is) in the same way so it's worth missing out on a bit of rock grovelling for a while, in my opinion... and I'm not that keen on babies in a general way.
