This thread is making me feel better!
Shortly after DD was born we moved into a new house and needed to buy a new bed. After much deliberation we decided to go with a king. I LOVE our bed. Love it. It is so comfy and roomy and delish! (Although, it doesn't feel all that roomy with a horizontal 16 month old in the middle).
However, I have had the worst case of buyers remorse about the bed. Beds cost serious $$$ and now that I SAHM money is a touchy issue for me. I think my stress about spending, combined with the feeling that we have been too decadent, has stopped me from seeing how much I really do love the bed, and appreciate the space. We travel often and have slept with DD in kings, queens and full beds. And I do like my bed!
