I find any "I know better than you" advice hard to take. From a mum, a grandma, a mum-of-1, a mum-of-4 (FFS! I KNOW you were told to put your baby onto solids earlier than 4m but I'm NOT GOING TO!) - if it's bad advice I will leave it with the giver. And you DON'T know better than I, no matter how many babies I have or you have because I am this babies mother and I know him best. I find multi-mums harder to deal with because "it worked for my four, control crying will work for you, you're too soft" - no. I actually love my children and don't want a "compliant" child so my hubby will be more interested in having more. I don't care if it worked for you or not, my family is different and it may not work for us! I'm not doing anything wrong if it doesn't work either, so don't try to tell me that.

On the flip side, I'll happily take advice from all sorts of people, including the childless and even *shock* men if it's well-meant and kindly given. How many children you have is irrelevent to if the advice is good or not.
