Will you give pen to lo at age of 16month old ? My mil keep on giving lo pen and I am not happy with it

Actually I think pen is not very good because of the ink and the sharp edge. I think a better close alternative could be to get LO those thick, non toxic crayon as it's bigger - easier for grasp and will not hurt themselves or others if they get agitated with it. Of course u can find other alternatives too - no need to be unhappy with it when changing the item can help :)
