My 3&4 year old daughters sleep in the same room. My 3 year old is very independent and wants her own bedroom on the other hand my 4 year old is very attached and don't want to sleep alone in her room. We live in a 2 bedroom house but with a toy room that could be used as a 3rd bedroom. Its not the first time she's brought it up. The first time I was like she's 3 shell forget in the morning but every now and then she brings it up. Does anyone have any advice on what I should do?
