When this baby is born I will have a freshly 2 year old. I don't know if I should buy another conversion crib (I'm guessing conversion kits plus mattress to make full bed probably around $200 total) or move her to an extra queen bed already in house with bed rails and change the current box spring to a low profile one to lower the whole bed.  Is she too young for this? I don't want to waste money on a second set of crib/mattress/conversion kits but I also don't want her to be unsafe. Does anyone have a 2 year old now who can tell me that they are ok in a big bed? Thank you!
