I didn't think you were supposed to put a blanket on when they are wearing gro bags?  You will find more information about what they should wear at certain temperatures on the grobags website - don't think I can give out website addresses.  Basically, if it's a temp of 18, you should have a 2.5tog with you lo wearing a babygrow and a vest.

hi if it is 17-19 degrees what do you put on lo in the growbag?

Yeah snap, thats how my ds sleeps... i was worried it was too much but he wakes with anything less. He does normally kick off his blanket by morning tho xxx

My lo is in a short sleeved vest, baby grow, 2.5 tog grow bag with a cellular blanket as well - I think its probably a similar temperature to you; a little bit nippy.

If it's 15 degrees now it'll prob get even colder!  I'd say a blanket on top should be ok!

its 15 degrees in nursery, so cool, i have my lo in a long sleeved vest, sleepsuit 2.5 grobag, do you think i need a blanket to? just draped a light cellular blanket over him! shall i take it off?
