I am getting married in Feb next year and we are only inviting relatives children (my cousins range from 4 yo up) we have a large family so finanicaly and space wise it just isnt possible to invite friends children. Our friends understand that. However bf bubs are certainly welcome as are formula fed babies for that matter, if i was FF a 4 week old I don't know if I would want to leave them at home either when they are so little. For me I think the no children at weddings rule would apply from 12months up JMO.

Personally I think its the couples wedding, their day and if they want to make it a child free, adult occasion then respect it. I would like to inivite some of my older cousins eg 10yo up but I know it would cause a huge issue as only 2 kids would not be invited. (these 2 are likely to be the ones running around destroyng things the 4yo punched my 21yo cousin in the face at my sisters 21st and wasnt told off by his parents grr). Hopefully he might have calmed down in a years time, if not im sure my grandmother will keep him in check.

When DD1 was 3 weeks I went to a wedding but it was at the couples house 5min from home, so mum looked after dd1 and I came home to feed twice worked well for us. This year I attended a wedding when dd2 was 8 weeks but the wedding was about 50min from home so she came with us DD1 was also invited but trying to entertain a 2yo and care for a new born at a wedding was going to be beyond me so dd1 stayed with grandparents. When Aimee started to cry in the ceremony DF took her for a walk. Wearing a halter neck dress to the wedding when bf wasnt a smart move though
