River school daycare experience

Hi - I am a first time mom to a 15 month old boy. I am thinking about starting daycare for my son in a month. He has been around me and my husband with grandparents staying for a few months. He loves to play with us but hasn't been around kids his age. He is also an extremely sensitive baby who is playing one second and then screaming on top of his lungs the next. I am very worried how he will adapt being in a daycare (also anxious about how I would adapt with him being away). River School, a bright horizons daycare in Newport, is closest to where we live and I have scheduled a tour for this week. I wanted to ask here if anyone has sent their kids to this daycare and if so, how has your experience been? Positives and negatives to be aware of while considering them? Any suggestions on how to approach this transition?
