14 month old always hurting himself?

Ka

My son has been walking for a month now and he is really good at it but he is always tripping on things like for example his cot he tripped on that which when he landed he landed on the edge of his change table now he has a massive big bruise on his eye and the other day he fell over and there was nothing he could have tripped on, just today he fell over three times!! My daughter never did any of that stuff every day he hurts himself weather it’s getting fingers in doors etc is this normal or should I be worried he has any problems? It just makes him so grumpy like even if he falls on his nappy he cracks the shits for ages.😭😭
