1. Indeed due to cultural differences, you could at least have it the same in western countries and pressure put on others. in america for example it is different from state to state which is absurd.
2. True though as an example I know a catholic family where the older children care for the younger ones, feed the babies change nappies etc. the age gap is equally detrimental as the nearer the ages are the more they relate to each other e.g. like brothers of say 8 and 10 would get on better than brothers of 8 and 16.
3. not at all, a 6 year old cant have kids, many 12 year olds cant, so it seams that nature sets the limit.
4. Something of semantics, those are what I would call childish activities. Surely we can simply class a child as not of potential parent age, again nature sets the limit. On this note I feel there should be differences in law and labels put on people, e.g. a paedophile is someone who has sex with ‘children’, hence you can have an AOC of 16/18 and another age of unlawful sex with ‘children’. many people have underage sex, but surely it is wrong to classify them all as monsters!
5. No I am saying that is unfortunate and very rare, we cannot have a universal rule to cover such things. She could have taken pregnancy tests!

We can have secondary rules for them, but we have a high proportion of teenage pregnancy in Britain anyway, so a distinction in law is necessary.
