Just got back from Tesco (Wigan) to find that they have various (own brand) baby sleeping bags reduced to £5.
They had them in 0-6m;6-12;12-18m and tog 1 and tog 2.5
There were various designs/cloures, suitable for a baby boy or girl.
Anyone who has used these before will know that they are great, and personally, I would never use traditional bedding on the wee fella, not till he's older anyway.
Hope this helps Mums and Dads.
