I bought my 13 month old daughter an awesome bed yesterday on craigslist. Step 2 princess castle bed. Can be toddler size or twin. I couldn't resist the great deal on it. She is a good sleeper. She asks for her bed at night. I just give a hug and put her in her crib and we blow kisses for a minute...thats it. She also loves her big brothers car toddler bed. Always in it! Even put herself down for naps in his bed a few times. But how young is too young ? can't decide how long I should wait to give her the awesome castle bed. My son was 2 yrs and 2 months old when I moved him to a toddler bed, but he didn't even start sleeping through the night till nearly 16 months old!!
