When your parents are helping you take care of your baby, it's inevitable you'll run into situations where you tell your parents "no no no, you don't do it this way" and your parents then respond to you "I did this when you were a baby, you came out just right didn't you?" And then you really can't do anything but shut up.

So far this is what I've noticed.

• Don't try to do full breast feeding unless the mother is literally overflowing with milk, else the grand parents will just keep saying their grand child ain't getting fed enough.
• Nowadays, baby bottle teats are made of silicon as well as the traditional latex. If your baby has any problems sucking from the bottle, the grand parents will comment that the teat is too hard cause silicon feels tougher than the latex teat which they fed you with. Then finally you realize that the actual problem is that your baby needs a teat with more holes in it.
• Your baby's pacifier keeps dropping, the grand parents take a look at it and says that it's too small/short compared to what you were using last time. You go to the shop and take a good close look at all the pacifiers in the market now. And all of them are small and short, must be because they realized previous pacifiers were too large and choked the baby.
