I'm going over to a friends place so am dressing LO in jeans and a long sleeved vest top thingy. We're going out for a long walk later and it's supposed to get to around 10C outside. What should I dress my LO in to keep him warm? I have a pram suit I could just pop him into as he's dressed now, or is that too warm? I could just add on a hoodie & a hat & warm blanket instead. What do you think?
