Ok so you've gotten your child a great toy. Do you just give it to your child and go " Here's your toy", and leave her/him to it? If you do, then chances are your child would not appreciate the toy given.
They say a mother is a child's first and best friend. So be just that. Give the toy in a fun way. Hide it somewhere easy and have him/her search for it. You can search too, but of course, you already know where it is. Well, mock search. Join your child in playing with the new toy, he'll subconsciously come to appreciate you and that toy. Have fun, laugh and roll around. When you have a kid, take that opportunity to be a kid with him/her.
