We use a gro bag also but i found maddy was cold with just the bag so we go like this!!!

-Singlet
-long sleeve suit
-gro-bag (mittens if really cold)
-sheet
-light blanket
-heavier blanket
ifts is REALLLYL cold ill add another light blanket, but we have heater set to not let house drop below 16deg at night so its normally ok...

Prior to me realising she was cold we didnt have the extra heavy blanket on there, now we dont get any 3-4am wake up (too often)
Maddy always has her arms up at night or she hugs her teddy so thats why we have mittnes on, although some morning they are soaked as she sucks her hands!!!


**leebee i hadnt thought of a cot blanket but thats a good idea - i too dont see the huge risk if its tucked in correctly.....**
