No athaan was given in babys ear when born

My daughter gave birth on Monday 17 Feb in the morning . She was premature and they put her in in the hicare unit. My son in law had the flu he could not go in and give Azaan and they did not allow me in. On Tuesday they put her on oxygen as she had breathing problems so they say. She was ok Tuesday evening when we left. On Wednesday morning they phoned at 2.30 and says she passed away. We buried her on Wednesday morning.
We decided on the name Lamies but no Azaan was given.
Please advice and what shall I tell my daughter to comfort her regarding the status of her deceased daughter?

Jazakallah
