I am getting a 9 week old boy this weekend. I live in Massachusetts and the past few weeks it has been cold (lows of 15 degrees F), and of course it will only continue to get colder. I was wondering what I should put on him when I take him outside? I bought him a coat already, but I was wondering about booties. The problem I have with the booties is I doubt that they are comfortable and when I put them on him he probably isnt going to want to go for a long walk. Also what are your opinions on temperatures that are too cold to bring him out in (if there are any), and any more ideas on keeping him warm outside.
