laugs i am so with you on the whole going with it with the second child. We were also much more conscious of making a specific choice over things with DD, it was much more 'clinical' though i guess, following 'rules' more, things being more precise, calculated, lots more books read! This time, still reading, things change, but more fluid about how and when things happen. Like weaning. I wanted initially to wait longer (he is 22 weeks on sat, 5 months exact today) but he is very ready and has been for while, so we just followed his lead, with DD, that lead was not so easy to spot. I don't think it is a bad thing to be more fluid with the second, i think its perhaps more 'natural' as we know what we are doing more sometimes. If he is eating the food and enjoying it, you are not doing the wrong thing at all. I am impressed with the whole weighing it out business though, i had never thought of that!
I gave him a lick of some apple puree this afternoon. I cooked up some bramleys to puree in my new whizzy processor, and DH insisted i could not feed it to him as it was too sour. He suggested sugar in it . I had this discussion with him re DD as she started eating. 'she can't have porridge with no sugar in, it is vile, it needs sweetening' no, you think it is vile, because your mother put sugar in all your food to get you to eat it, DD knows no different' Even now, i never put sugar on any of her food, he does, she eats them both the same. anyway I put a little on my finger, and he grabbed my hand before i could touch his lips with it, and shoved it in his mouth!!! He licked his lips, opened his mouth, looked curious, then his eyes went ping! and he wanted more! (and DD ate two bowls full of the too sour apple wink]). He just absolutely loved it, but resisted the temptation of giving him more than that lick as he had already eaten a million spoonfuls of carrot for lunch.
