This.
Can I also add my two-pennoth of "proud new father" wisdom gained those twenty-odd years ago now - when your young-uns get to the age where they want to be carried everywhere, for gods sake buy something that allows you to carry them in a balanced way, something like a papoose mentioned earlier.
My mistake was to want to carry both of ours around various supermarkets in one arm in that classic stance where you park their bum on one hip so that you've got one arm free - big mistake as it twists your spine in the opposite direction and you end up over a 12 month period with a crushed disc at the base of your spine, ten weeks recovery by not being able to move at all and then years worth of back problems and a dead spot in one of your legs from nerves that were shot.
Apart from that - enjoy your little sprog and savour every minute, they grow up far too quickly and the next twenty years will fly by.
