[MCU] Why didn't Thanos send any of his children to keep an eye on Loki during the invasion of New York?

So in GotG, an incident involving a single infinity stone requires Thanos sends 2 of his most trusted spies and children to keep a close eye on Ronan who has notoriously bad temper. Thats fair enough, theres only 6 of these in all the universe and Thanos really dosent want to fuck this one up.

But in Avengers 1, gambling the only stone you own to gain a second (possibly a third if he knows about the time stone), particularly to the motherfucking God of Trickery of all people dosen't warrant such supervision?

Considering Loki was much easier to intimidate than Ronan, having one or more of his children present would serve as an effective reminder to Loki not to try anything stupid like undermine Thanos or >!escape with the one stone that lets you teleport to anywhere and escape as far from Thanos as possible!<

Why did Loki seem entirely unsupervised aside from the hordes of Chitauri wheras Ronan has Thanos' immediate (adopted) family involved?

Probably because he knew Loki didn’t want the stone, he wanted Earth, which Thanos would be fine to turn over to Loki after a culling. He didn’t think Loki needed oversight because he underestimated Earth’s/humanity’s ability to defend itself. If Loki got out of hand, he could easily turn his children and the Chitauri on him.

Ronan, on the other hand, did not just want Xandar. He wanted absolute power for the Kree. Far more likely to betray Thanos, because while Loki is slippery, Ronan is mad.

Plus, GOTG takes place after Avengers, so arguably Thanos learned from the Loki experiment never to play a game like that again without sending his children as insurance.
