It's quite normal,some people use left hand as normally as we use right hand,guide your baby that he is using wrong hand,tell that to use right hand for writing, drawing, eating...you too show your baby how you are using right hand,you need to explain your baby,if not confusion occurs,so don't force your baby to use right hand only if your baby is not comfortable,I heard that left handers are quite sharp and intelligent...

If you want him to improve his writing, let him play with small blocks and give him playdoe to strengthen his muscles in his hands.Let him use big paintbrushes, big pieces of chalk and even his finger) to practice letters and numbers. These methods are more fun and he will not feel frusterated. This seems more fun than more (always present it as a fun way). In his own time, he will learn how to write. Encourage by reading as much as you can and let him do scribbling! In fact draw scribbles like him and incorporate a real letter or number in it.
Eventually he will be a good writer.Yes it can be leggible, but dont expect perfection. Just encourage and have fun!👍
