When did you first feel your baby moving??

I am at 16 wks 5 days today.. I work ft and I got 4 kids already.  Today I actually took a lil break from everything and just layed  in bed and watch tv.   I am more than sure that I felt my baby moving.  Just wondering is this consider too early to actually feel my baby moving?  How far along were you guys when u first felt your baby moved????  Best part to being pregnant! 😊
