Co sleeping with our 1 year old????

Lindsay • Enjoying every second of our beautiful baby girl

So my daughter slept in her crib in her own room from like 1 month old or something crazy. She's 15 months old now and for the past 3 months she's been in our bed! It started out that I would let her nap with me, then one day she got an ear infection and was super sick so we let her sleep with us at night for like 2 or 3 nights in a row to monitor her. It was pretty much downhill from there!!! For a little while we were letting her fall asleep with us and then taking her to her bed where she would sleep through the night but eventually she started waking up and realizing we were gone so she would freak out and end up back in our bed. So basically our sleep situation has totally regressed and we are 100% to blame because we both admitted to each other the other day that we both secretly love having our little stinker in bed with us 😩😭😩😩 Are we ruining her?!?? Or is it harmless? Opinions?
