Hi Personally I don't see four as such a big number, I come from a family of nine, the youngest is eight, I wonder how many comments my mum had! I'm having number 4 now and most people say wow 4 your game, things like that, my Mum was over the moon about it, my MIL was a bit worried by it but she's coming around, I'm getting a lot of comments I bet it's a boy this time (I've got 3 girls) or I guess your trying for a boy, actually we just want a baby, we don't mind if we have a girl I've got a friend with four kids and she's trying for #5 and her family think she's lost the plot and most people are negative about it, but if she wants 5, then what's the problem. The worlds gone mad if you ask me I'm having my four a that's that I'm getting my tubes tied this time though, only because this will be my fourth caeser....
Good luck, be happy and don't worry about other people's comments, what do they know....
