We recently returned from oman...was amazing and stayed at al bustan hotel. They hAve babysitters you can use during the day whilst you sit by the pool.
We met a lovely couple who were also there with same age kids (6 months and 3) and they were raving about one and only royal mirage in Dubai...so that's where we are hoping to go to next.
In oman the shangri la is really child friendly and we went to see it...much preferred the al bustan!
