Ignorance is bliss!
A real theme here is how mothers worry too much these days and should just chill out and listen to the old folk who just knew best because they just did and people should stop interfering.
The reason we're told how to put babies to sleep on their backs etc is because children died when people just did what worked/felt right.
The reason parents are told how to prepare and keep formula is because children died when it wasn't done right.
The reason the HV comes to your house is to stop children dying because of these things, to prevent abuse and neglect and catch any problems to help kids as soon as possible. Don't take it personally! Be grateful that a baby won't die from being shaken because the HV picked up that the parents needed a bit of help. And that is fine! It's not just you and your baby that matters.
These guidelines are based on what has really happened in the past. People who say "my kids turned out fine" drive me crazy. It's not just about your kids! And did you ever consider you're just lucky?
Of course mums are fearful in a world where the things our parents did caused babies to die. It's a horrifying thought that we could kill our own children by putting them to sleep the wrong way in a house where someone smokes. How can we not read the very available information that will keep our babies safe? How can we not be anxious to get it right and keep them safe?
Of course things were easier without the knowledge we have now. As I previously said, things that would be considered neglect were just normal!
You would never hit a child now! It's against the law in some countries. It was very normal for me and my friends growing up though. I still despise my parents for it.
Maybe what the older parents are missing here too is a kids view of growing up then. I hated being bored all the time. I hated "go play in the garden" again and again. I really hated being hit. Perhaps the reason parents run around keeping their kids entertained and paying attention to them and loving them is simply that things weren't so great in the good old days? Maybe they want better things for their own children?
I agree that life was more physically demanding and fair enough if you need to get work done then you need to, but let's not pretend it's better for children to be ignored while you wander off and visit the neighbours or whatever.
