I have a Moby style wrap that I bought off ebay. It's a stretch jersey material. It is quite a warm day today and my LO was really hot inside the wrap and he was only wearing a vest. Is this normal for these style wraps? I really want to be able to wear him, I also have a pouch style bag but he ends to use this with OH and a Mothercare rucksack style one but we will use that when he is older.
