Childhood life was the best part of the life of a person. Innocent faces and mind was the feature of an Innocent child. At this point no problems to worry as long as you have a playmate. As far as i could remember i have no favorite toys. As long as i have a toy to play and playmates i am happy and satisfied. Yes! toys can make a chiold happy as long as they like it. But as i observe if the toy they are playing with is not their favorite they just through it side by side and they are not contented of what they have. So a little concern from me let the child select of what toys they want to buy so that the money that will be spent on that thing wont waste.
