Does anyone have this? I have had the Tripp Trapp chair and baby set since my toddler was 5 months and absolutely love it. With number 2 on the way I'm considering the newborn set but haven't seen it anywhere in person, just online. Am keen to see whether it can be used for daytime naps - is it lie flat or is it a bit like sitting in a car seat? It's a bit difficult to see from the pics. Looks good for keeping the baby up high and out of the way of inquisitive toddlers?!
