Sounds so frustrating for you.

I echo what everyone else has said - your bub sounds normal. It is a myth that all babies sleep through by a few months of age. Have you tried carrying her around in a sling or baby carrier?

You can ring the ABA helpline like Barb suggested, or if you feel that it is a medical issue (e.g. silent reflux), then maybe go see your GP. GL. Parenting is hard, but it does get easier. This too shall pass.
