You know that you are welcome to take your kids along with you to the meetings if you want to. So long as they are not disruptive. Alot of kids enjoy joining in, whilst others just sit in the background and read or colour in - and if you want you can just go and weigh in and then leave straight after, not actually staying for the meeting.

Having said that, the online tools are fabulous on their own. I know many people who have just used the online tools successfully. I would recommend going to a chemist or a dr surgery or somewhere at the same time each week (most places like chemists and drs are happy to let you do this for free) or even a friends house, as it gives you accountability (it is different weighing in front of someone else, rather then just on your own bathroom scales). There are also forums on the weightwatchers website, they provide a wealth of information, however aren't (IMHO) very well moderated; so be sure to take whatever is said with a grain of salt and try to get a couple of opinions (especially is something sounds to good to be true).

I attend meetings probably every second week, but I use my iphone app (which is free with etools) constantly throughout the day, it is what keeps me on track.
