The Asda baby sleeping bag provides 2.5 tog of warmth and has a quilted inner to keep baby nice a snug, a job it does very well. I love baby sleeping bags because I find it so much easier than using blankets and worrying about them smothering themselves or kicking them off and getting cold. Also, they can wriggle and roll around into whatever position is most comfortable without any problems! My son is very happy in it and I haven''t noticed many differences even though we primarily use another more expensive brand. The design is lovely and it''s nice to have a different design on the front (stars) than on the back (stripes). It seems pretty spacious, but on comparing it to one of the others it is noticeably smaller, and the one we have is suitable from 6-12 months, whereas others last through 6-18 months. One thing I have noticed is that after only a handful of times in the washer and dryer it has started to bobble all over, which isn''t a big thing just a bit disappointing that it doesn''t stay as nice for long.
