Dts are now 8 months (6 corrected) have now got quite strong grips, espically Ds who has perfected the neck skin grab and twist, ouch! A couple of times when I've put them down together on a playmat etc I've had to move one away because the other has been going to grab their nose/eyes/ear etc. They usually share a cot, is there any chance they could actually damage each others eyes at all?
