I see! It is a really good idea to get her looked at by an LC. Was she prem? Jaundiced? Any other health issues? How often is she feeding? What is her poo output like? Has she been assessed for tongue or lip tie, problems with her palate?
You can also call the ABA helpline to have a chat with a counsellor - 1800-686-268

It's great that you're getting the milk into her! Good work.
