Actually, if an 8 mth old hit another 8 mth old, then I doubt that anyone would be up in arms 'regardless of who did the hitting'.
The thing that's got everyone all riled up is the fact that it was an older (actual age rather than ability to understand age) child who did the hitting.
The fact that the autistic child doesn't have the understanding everyone expects from a child that age and therefore cannot be held accountable for the situation coupled with neither of the mums in question 'being psychic' seems to be a stumbling block for some.
Errmm......... Since no-one is psychic in the scenario, and we cannot blame either of the children for their actions or reactions, again I say no-one was at fault, and both mums were present but couldn't predict the hit would happen!
Please can everyone have a little tolerance and sympathy for everyone involved ! No-one planned this, no-one expected this, and no-one could've stopped this because of that !
Since everyone would seem to physically OK, can everyone not simply sympathise and empathise ? Both mums will have to cope with a whole lot more in life with their respective DC (e.g older kids bullying, school problems, health problems, childcare, blah blah...... all the other issues that crop up on mumsnet) can't they simply be having a stressed out, crappy day and move on with life without dissecting every little detail and apportioning blame to someone? IT WAS NO-ONES FAULT !!!!
Sheesh, the blame culture gone mad !
