Im in a similar situation to you hun
I co-slept with my daughter (now 23 months) from birth till 18 months when she went into her own bed in her brothers room. She still gets up some nights and climbs in with us, which I dont really mind too much.
I still have my cotbed set up as bedside sleeper so she tends to end up in there. I know I should start taking her back to her own bed, but she screams and cries so loud if I try that she wakes her big brother and he gets upset too!
Im just going to see how it goes tbh (thankfully we have a kingsize bed)
I dont want her to feel pushed out either
