Hi, I'm just after some advice please on clothing for the cold months for my September born LB as I'm pretty clueless! 
What is the difference between a pramsuit and a snowsuit? Do we need both? I plan to walk him (and the dog!) outside in the pram regularly and occasionally in a carrier. Would you also get a Cosy Toes type piece for the pram? And any other top tips/buys? TIA
