Never say never...
never say never or that you wouldnt ever try a certain form of discipline or childrens product/device until youve been in a situation where you really needed to use it. Does that make sense?
If you have one child who is 2 months old and you say, "i will never spank my child!" Wait until that child is two and bites you on the side of your fat roll... I promise you, your hand will move quicker to that childs butt than you would ever have thought lol.
Or... Ill never use a child harness. Wait until your in a situation where your toddler screams every time shes in the stroller and throws herself out of it in a crowded place. Snap snap click, shes in a harness. Better than being snatched up by some crazy person.
