Mama, who told you to be worried about this? Somebody is not being nice to you if they said there is something wrong with him not walking. You should be perfectly content for him to be standing and holding on to things. Soon, if he isn't already, he'll be cruising, walking while he holds on.
You know how babies have milestones they master, like turning over, pulling their heads up while on their tummies, scooting on the floor, then crawling on the floor, then pulling up to a knee position, then to a standing position? Well, then comes the cruising, and then finally, the walking. While these physical milestones are being met, they also start language. Sometimes when they are really focusing on one milestone, the other gets left behind for a while. So some children stop trying to talk when they are trying to walk, and vice versa. Learning to walk and to talk is very hard, Mama.
In your child's instance, he is VERY young to meet either the talking or the walking milestone. I urge you to ask your ped or look up childhood development to negate whatever people are saying to make you worried that he isn't walking yet or just because you want him to. He has to be ready for this physically and in his brain. And no amount of wishing is going to make it so.
Don't put him in the position to cry with walking - it's a real mistake for you to do this. I know you didn't know any better, but you do now. If you doubt what I'm saying, show your pediatrician this thread and he or she will let you know what's right.
All my best,
