Well I've finally got round to buying a 2.5 tog grobag for ds (aged nearly 3 months) and will start using it soon. But the little thermometer that comes with it suggests bodysuit and pyjama tops only for 18C-ish and higher. Do you really do this or is the usual combo of a bodysuit and babygro ok - I've got loads of them and don't particularly want to buy pyjamas as well.
