At our wedding, we had 8 children aged 7 and younger. I had my aunt (who is very handy with a sewing machine) make fabric bags with each of the children's names on them. I then filled these with lots of activity and colouring in books, depending on the ages of the children. The Tate Modern's book store which has loads of activity books was a really good source of inspiration in this regard. I ended up buying books like: Everybody's activity book The anti-colouring in book; and The ha ha bonk book (a favourite of mine when I was around 7); and for the younger children (we had quite a few between the ages of 2 months and 3): Peppa Pig Activity Books The Hungry caterpillar Tell Me How Much I Love You; and Jonathan and Martha We also gave the babies a small soft toy each. I agree with the comments above re: bubbles. Disposable cameras are also a very good way of keeping children entertained, and my mother in law also bought a pack of silly moustaches, glasses and noses, which went down a treat with the toddlers... We also had a retro sweets table and a fancy dress box (including glo sticks) for the evening bit of the reception, which went down a treat with the slightly older children and adults alike, and I'm sure the sugar high meant that our little flowergirls (aged 5 and 7) stayed dancing far later than they would otherwise have done - which was a bonus for their parents... In a similar vein, I've also been to quite a few weddings which have had photobooths (both DIY and professional) and these also seem to go down a treat with children... Also, if you google "Rockmywedding windswept beauty part 2" you should stumble upon a blog entry for a beautiful scottish island wedding where the couple had a table of toys and games etc. set up for the children - a fab idea and one that in hindsight I wish I'd thought of earlier... Happy planning!
