Do i really need to wear all of this?

ok i am 14 and am going camping this weekend for the first time ever with my mum dad and older bro :(
me and my mam were talking about it and she seems to think i will have to wear all of this just to go to sleep??

a thin pair of pj’s, a thick pair, a jumper then 2 hoodies and a thick puffy coat thing. Then like in a sleeping bag with a quilt over???
we are not going anywhere really cold, just a normal campsite.
although i have never camped before this seems a little over the top?
My parents usually think its funny to do things like this, they know i don’t like being too hot so they do things like, put the heating on in the car on a long journey just to see me annoyed , and things like making me wear lots of layers.
My mum also threatened to make me wear more if i complained about wearing this amount!

what do u think??? thanks xxx
