Administrative data on Birth Weight

Does anyone know of data sources that have birth-weight data of children, their date of birth, etc. in the context of a Muslim-majority country? Ideally this should be high frequency administrative data - such that it can be looked into as a potential outcome variable for a health intervention. I'd really appreciate any feedback.
Any DSS/HDSS type of data might help. But I'd appreciate some direction on how to access the data.
