It's like pushing a pea with your nose up Everest. Unless you've been a parent or cared for toddlers/siblings it's difficult to fully appreciate. To answer 'first mate's' question I would say that if the toddler is in any location (doesn't need to be a pub) that is threatening to them and at a time when they need sleep/feeding or both then they're not going to get much positive out of it. There are a small minority of parents, from all sections of society that don't always exercise good judgement. It's a shame that that small minority can often spoil things for many others. Often though it's simply not the fault of the parents. On a nice warm summer evening, in a beer garden/restaurant/cafe/whatever, with friends/family at a reasonable hour (not later than 8pm IMO) then I think it's a positive environment for toddlers to socialise and be introduced to different environments and people. Kids are kids so their behaviour is never going to be exemplary (same as us adults). During their development, they'll either be frustrated at a lack of ability to be able to express themselves articulately, hence the screaming, a need for attention (aka all youngsters in the animal kingdom) or full of curiosity to push beyond the boundaries set by their parents. All qualities that endear us at all ages. If we were a more kid/family friendly society I wonder what the statistics for teenage knife murders would be?
