I have the same issue with weekends, because I'm not at work there's no structure. Keep yourself busy, if you're anything like me, you tend to eat more because you're a bit bored rather than because you're actually hungry! There are some brilliant naughty items that are low Syn in case you feel the need for a treat - Velvet crunch crisps for example are only 4 Syns, but feel naughty! If you're worried about carrot sticks etc getting boring, add some low calorie/low fat hummus and dip, it'll take you longer to eat, be more filling and a lot less boring!
How old are your kids? You can maybe get them involved in cooking some low syn treats? Then they'll be entertained, you wont be bored/have time to snack and you can enjoy the end result without feeling guilty!
Remember healthy fruit and veg doesn't have to be boring - I was totally against the idea of snacking on fruit and veg when I started, but you can make them interesting and I actually find myself looking forward to a veggie snack now!
Good luck!
