The limit of 3 caesar's is only a recommendation! You can have as many as you want, just be aware when you fall pg that each caesar after 3 gets riskier and riskier, akin to having a VB (VBA3C or vaginal birth after 3 caesars).

Many womyn have gone and birthed large babies, larger than 10lb so I'm not of the belief that a baby will be too big for Mum to birth (unless there are complications that make baby overly large, ie. GD) and that the female body can do amazing things during pregnancy and labour.

I have a friend who has had 5 caesars (one set of twins) and know of plenty more, so it does happen.

I will be birthing my third baby after having 2 caesars, not just because I want more children either (my babies aren't that small either, 8lb and 9lb (the 8lb was 3 weeks early too) so I'm not expecting a small baby!

Cheers,

Beck
