dozens hang with their kids, mine at 4 years of age - is about to go on his first overnight hang.
the only issue is that its best to downsize the gear, which is cheap and a DIY option or ask someone to make it for you.
1) ripstop seconds, 1.1 oz
2) no seem mesh as a "sock" (not sewn to hammock, but like a full coverage barrier, that can be left behind when bugs not an issue-hammock ridgeline required)
3) whoopie slings. dont ask, just get them. do it.
4) many partial UQ's are full length on children.
5) any sizable tarp can be pitched to accommodate 2 or more hammocks.
