My baby is now 1 yr old and trying to walk. She got hurt many times. Sometimes we had to rush her to the pediatrician. Mostly she used to hurt her tongue, cheek and head. My parents and I cannot prevent her from falling. Sometimes out of frustration I used to think we should put some kind of helmet on her. Please suggest some thing which will protect her from getting hurt.
While falling and getting hurt are part of learning to walk. Here are a few tips that may help:
A helmet is not advised as it could slip and cause injury to head or neck.
Our little one has had some nasty falls – face hitting both shelves of the coffee table, face into a fence pole (blood nose, trip to hospital), falling backwards off couch – and many many smaller ones. For the smaller ones, like the ones you describe, she sometimes cries, sometimes just says "bonk" and sometimes is furious. But she always reacts promptly and normally, so we know that nothing is wrong, even though it looks bad.
Kids fall. It's a part of learning about the world. Just may your world safe so that when they fall, they are less likely to do any severe damage. Ironically, they will learn to walk better if the environment is not too 'padded'. They might start tripping over the edge of the rug, but don't take the rug away, as it acts as a device to teach them how to walk more stably. Same goes with socks and somewhat slippery floor, and sand and bark, and walking on a trampoline. They're all more difficult than basic walking, but they help the child learn to walk better.
And learn to worry less about it.
