Bit late I know but there is only 1 hospital I would recommend and that is Danat. Excellent doctors and midwives. In recent survey by DoH of all maternity services across Abu Dhabi this hospital came out way ahead of the rest. You may have to wait longer than you would like at times in the OPD but that's because they are popular. Also if you request a midwife delivery or hypobirthing etc they will accommodate.
I had a fantastic experience there twice and the after care by the paediatrics is second to none
