When Mum gets baby ready to go out;
She will look out the window to check the weather, if it's not glaringly obvious through the window she will open the door to double check the temperature. Once deciding on the weather she will make her way to the wardrobe (or pile of clothes that I'm yet to put away if I'm talking about myself...) and spend several minutes picking out a top/dress/bottoms/socks/tights that all match. Once that is sorted she will look out the window once again to decide whether a vest is necessary under the selected items. She will then begin to dress baby, including changing nappy and washing face, once baby is dressed she will then pick out a 'nice' bib that is stain free just in case it's needed.
She will then pick up changing bag and check there is enough nappies, then add one more in case, check there is 2-3 clean bibs, a bottle, a dummy, sun lotion (even if its not sunny because you never know!) wipes, sudocrem (or the equivalent), nappy sacks, spare clothes, a toy, the camera, her purse. then spend another minute re-checking the bag and making sure everything fits in nicely.
On leaving the house she will then feel baby's hands/face/feet several times to check that baby is the right temperature.
When Dad gets baby ready to go out;
He will go to the nearest pile of washed clothes and pick out the top item oblivious to the temperature, leave nappy on unless it smells really bad, dress baby, remember he's forgot the socks so put the nearest ones on regardless of their colour or whether they are a pair. He will glance in the change bag and see there is at least one nappy in there. Leave house. remember they need a bib, return to house and pick up the same bib that was used for breakfast, food stains and all. Leave house again.
And even though baby survives completely fine when Dad does it we will never change our way.
