My two little ones are turning 3 in may and turning one this month. They are currently sleeping in their own bedrooms. My youngest sleeps quite good on her own,the older one comes to us at night (not every night but most nights) because she wakes up and doesn't want to be alone. She doesn't cry or anything but I just let her sleep with me because what's the point of sending her back lol.

I was thinking maybe she'd stay in her room if they are both in one room together but I also would be scared that they wake each other. My youngest still wakes up 2-3 times to be breastfed at night. So I'll definitely wait until she's sleeping through or only waking up once. But I just wanted to know what other people experienced what the best time is for kids to share a room?
