Not even when you are buying toys for them. I was reminded of this when shopping yesterday. A family had come to shop with their little daughter and this little girl Sees something she likes and tells her father she wants it. Dad says no. The girl insists. Dad says no and the girl starts screaming, flinging items on display off the shelves . . . It was embarrassing for the family. A discipline issue yes but even if your kid isn't as bad as this one, kids can nag you so much that you have to buy them something which isn't on your shopping list. Even if you say no and mean it, it won't make for a pleasant shopping experience having to walk around with a grumpy child.
