Not sure if I have any advise that will help, but I only wanted DH at the birth let mum know. I have a good relationship with my mum, thought she understood, rang her when my water broke so she would know we where going to the hospital. She turned up at he hospital nurse told me and my husband said to show her in. I honestly didn't even notice she was there, she just sat quietly in the room and was beside the bed when I started pushing. Think she thought my DH would be thoughless and not be there for me when I need him, just from some conversations we have had since.

Don't stress about it is a time for you and baby.
