Now, horror of horrors! I am one of those parents! We sometimes would buy the kids the same toy or book or whatever
For example, sometimes, when we see a nice book (which the boy isn't developmental ready to read yet) or which is more more suitable for the girl so we buy it for her. We would tell the boy. "No, sometimes we buy things for you and sometimes for your cheh cheh (sister)." when he insists that he wants one too.
Or we would have this scenario. "Mummy, I only have 2 books, he has 3!" "How come he has and I don't have?!" Then we would say "No, sometimes we buy things for you and sometimes for baby."
Well, we do try our best not to be taken in by their sad faces and our guilt. We try to be fair and all but sometimes we buy two of everything. *guilty*
