We are going camping for two nights next week and I am always freezing so I was telling DH what i was bringing for the DT's (they turn 3 next week) to sleep in/wear and he thinks they will be too hot so I just wanted your expert opinions 
Thick cotton rug on floor, then ready beds lined with a fleece blanket to stop the cold coming through, then fleece PJ's and vest and thick socks, then the shitty ready bed "blanket" and a toddler quilt on top. Too much?? It's supposed to be sunny but only 18C during the day so I think it will drop quite a lot. And since they get up at ass face (so named because that's what my face looks like at 5am) O'Clock anyway I am trying to stop them waking up any earlier because they are cold.
Also any recs for night lights for them? I don't want them freaking out if they do wake up and can't see where they are. Would some little solar fairy lights give off enough light for them?
TIA
