Will my 7 month old baby remember her aunt’s face?

Today I am busy and the only person free to watch after my 7 month old daughter is my sister. My sister visited us every single week but we have not seen her in 5 weeks because she has been in Australia but she is back now. My baby is good when she is alone with her dad and grandparents, and she was always fine when alone with my sister. Will my baby remember her aunt’s face after 5 weeks? I’m just worried she will cry or won’t behave because she doesn’t remember her or feel comfortable :(
