Yrs to all the toys.
When ds1 was little I was all 'no toy guns etc' but he would use a stick as a gun or a banana or bite his toast into a gun shape or build one out of duplo etc so I got a grip,
They love nerd guns, we currently have no bullets though they lose them easily! Toy guns but one's that obviously look like toys, they often choose them if they win a prize at the fair hook a duck type thing.
Toy army figures they have some of dps old ones and we bought a few other bits, they are interchangeable with their knights and castyle figures (shcleich ones).
Toy swords and shields send light sabers a go go here!
And we have been to many lazer quest pparties and ds2 has had a blazer quest party.
They also have toy bow and arrows/archery sets, national trust one's.
They know not to point them at other people and that they are pretend. They also know real guns kill.
I think an interest in guns and warfare and goodies and baddies etc is quite a normal phase for all children to go through.
My daughter plays with the guns and swords etc as well as the four boys.
