I found out that when ever my family members were Tired/Exhausted, sending them to bed did not boost their energy. But when I took them to take nap, it did. Did it occur to you guys too? I'm just curious. Will relaxing at the hammock can boost the energy too?

How do you get them to take a nap? If a peep is tired/exhausted dropping them on their bed will usually send them to bed, but I've never found a way to get them to nap. Both going to bed and taking a nap seem to increase my peeps' energy levels. The hammock doesn't seem to make much difference, but I've not checked to be sure.

I just drag them to the sofas. But I have to drag them many times until their action changes to "Taking a nap"

Then this is just an incident because the actions of the peeps are mostly random.

i make mine take naps also, i usually drag them to the chair though. sending them to bed raises their energy levels a little bit but not nearly as much as the naps do!

You might just as well pick them up and drop them anywhere. Eventually they will decide to take a nap if their energy levels are low.

In the first version, the chair would make them nap about 95% of the time. Since the .05 update it takes FOREVER to get the nap option to come up, so I began to praise mine any time I see one of them do it, from anywhere in the house (even when I don't actually let them nap at that time.) That seems to make it a little faster to come up when I DO want them to nap. The chair always seemed easier than the sofas, even in the first version the sofas seemed to trigger watching tv more than taking a nap. Regardless, I have to say I still do believe the chair and sofas are hotspots for nap taking.
I also agree that nap taking is much more effective at short term energy regeneration than going to bed. Going to bed is only effective if you are going to close the family and not open it again for several hours. In other words, it's really better to let them do it on their own (in my experience, at least.)
Edit: I never noticed any use for the hammock whatsoever, in either version of the game. Although there was much talk of it being helpful for the tired/exhausted issues with the first version of the game here on the forums, I never noticed any increase in energy levels of any of my lil peeps who used it. That has not changed with version .05.

ya i think that there isn't a way to make them take a nap....

..yes, i do find that to be true as well...

...Ahhh, i see. (question answered) Thanks!
