Actually,it was June.Caylee and KC had many sleepovers at Ricardo's in May and June,including the one where Caylee was gone in the morning,according to ricardo's LE interview.

I don't think it was in June. I just re-read the interview that you provided the link for and the relevant portion reads:
DR: Okay. So on the, do you remember when that was about uh, her bringing Caylee home in the middle of the night?
RM: I really dont know.
DR: It was when you were still dating?
RM: We were still dating uhm, but
DR: Back in April? Before that?
RM: I wouldnt be able to say. I would uh
RM clearly doesn't remember exactly when it was but in other portions of the interview he goes into great detail about what happened during and after the sleepovers in June so I think the taking Caylee home night was back when RM and KC were officially dating.
Also, even though CA disputes this, I trust RM, who does not have any reason to lie about it, over CA who did not want to admit to the public that KC was out and about in the middle of the night with Caylee and that she knew about it.
And since all of this is slightly OT, I'll add that nothing has given me any reason to believe that Caylee was ever put in the trunk alive because 1) KC and Caylee's movements seem to be accounted for by pings and other evidence, 2) Caylee would not have survived very long at all in the trunk, 3) A lot of people mentioned that Caylee had separation issues at bedtime and I can't imagine that it could have been very feasible to transfer a sleeping Caylee to the trunk without waking her up unless she were heavily drugged. Then, where would the act of placing her in the trunk take place? In the garage at the Anthony house? In that case she would have had to take her out of the house already asleep and drive around with her rolling around in the trunk (not that she didn't do it after Caylee was already dead, but driving around with a live child in your trunk seems to be begging for even a drugged child to wake up). Did she put her in the trunk in the parking lot of Tony's apartments? Obvious logistical problems there.
There just doesn't seem to be any reason to believe KC ever used the trunk for anything other than normal trunk uses, a temporary trashcan, or a temporary coffin.
