Sarah, I know some babies love them and others hate them, plus they are hard to find ('speciallay in a size 1 and 2) but Bonds Cosy Cuff suits have cotton mittens at the end of the arms which you can fold over their little hands.....

Because Olivia spent her first 14 months in a topical climate, she really hates the cold, so we use these. And we have also resorted to a radiator in her room that we leave on very low overnight (where we live in Adelaide is v.high up and gets down to 6`c at night.......)
