Hey Ritta, my son (22 months) has been enrolled in babilou umm suqeim since April and I can only say that we re happy with it. Am a working mom and as you've mentioned the fact that they're quite flexible in terms of opening hours, days and food was a + which made our life easier. Team/teachers are great and very professional. My son integrated after a few days and loves it.
I can only relate when you say it is the first time you're leaving your baby - wasn't easy for me neither... but the team kept me in the loop with regular calls and updates on their app + the nursery is super safe which was reassuring at the time as it was also my first time leaving him more than a couple of hours!
Hope this helps... good luck!
