Hi mums

Just wondering if anyone has any tips for me. My 2 1/2 year old daughter is going through a phase where she wakes in the night and comes into my room and wants to get into my bed. I am back and forth putting her back into her own bed but give it 3 mins and she’s back in the room. This can sometimes go on for about an hour and she ends up in my bed or on my bedroom floor but tonight has been 2 hours. I’ve now compromised and put her mattress on my bedroom floor so she can sleep there just so I can get some sleep but this has been going on for weeks now and I’m so tired and stuck on what to do. Is anyone or has anyone going/gone through this. Worse than a newborn - Help 😭
