Having 2 children 16months and 4 I know what it's like, but we've been lucky. Maddie loves going to a cafe or Gafe as she tends to call it and get a hot chocolate. She's pretty well behaved and tends to be easily amused Hamish is to young to know better but generally timing works out that he gets a bottle so he's happy.
I've seem parents let their kids run around carrying on like right little a holes and I really don't understand the parenting. We take crayons and paper to let her draw even when we go out to dinner and it always works out well but a lot of parents seem to think it is their down time and it is everyone else's turn to put up with their kids.
Brunswick has an awesome cafe, the back area is under cover and has a large kids play area. We've been there a couple times and it was great but again you get 'A-Hole' parents who's kids don't play we'll with others and you have to either parent their children or take your child away which is BS.
