Sleeping Bag USA

.. my son be wearing to sleep? im not from the uk/usa and its not freezing here but it gets colder at night just the same. last night my son wore a vest, thinish babygro and the wooly pyjama (mothercare) and he actually gave me the best night so far by sleepin for 3 hours in his own bed! (for once) -- n thats a lot for him! lol.
what does ur baby wear? do u find the sleepin bag better? theres no heater anywer in the house btw.
he's 6 months.

thanks xx
my doc told me it should be this temp n i hav no way of heating it up unfortunately.

i tried him with a banket but he manages to shuffle around n pull it to his face so if i dnt use one :/
*sry dnu how the "if" got in there!
