my opinion is to visit a dentist and get the lower milk tooth removed.
The lower permanent incisors usually starts erupting by the age 6 yrs,
some may take +/- 3-6 months more for the teeth to fall.
in your sons case , since the permanent teeth is erupting behind the milk teeth ,there is no hope that the milk teeth roots may resorb to cause it to loosen ,hence i advice you to get the milk tooth extracted.
there is no side effects of such removal and is usually a normal procedure done at the dentist s office
