Parenting advice

Was reading a few of parenting experience sort of advice from other ppl. Tapi yelah. Tak semua will face the same thing. Cuma kita as parents kena pandai control situation. The topic was like "discipline starts from HOME" . It is true. Tapi kalo in one house got so many ppl say this say that, eg: mummy, aunties, uncles, grannies, mcm mana eh? Kalo i pun pening. Nk ikut which method?
