I’m going to have to follow this thread closely because I imagine we will be in the same boat very soon. We also have a 3.5 year old that thinks our bed is the place to be. She actually told me that our bed is a “10” comfortable and her’s is only a “1” comfortable. She almost won me over with her logic and reasoning, but we’d prefer she sleeps in her own bed. We also have 5.5 month old twins who I’m sure will be teething within the next couple of months. Good luck to you mamas in the trenches right now!
