Mods please move this if it is in the wrong place...

I am just curious as to what 'others' opinion is on "first time mums giving advice to mums of mulitlpe children" and how do you take their advice?
Just lately a heap of advice has been given to me by a first time mum who obviously thinks she is an encyclopedia.... and that 'i' know nothing..BUT hang on..i have already raised a 9 year old (nearly 10) and an 8 year old..
it really irks me.. thinking they know best.
sorry bit of a vent...
