1mo old advanced or normal? Anyone else’s baby do anything that surprises you?

FTM here and I don’t know whether my baby is advanced for her age or if these are normal milestones.

Came out the womb being able to hold her head up

She has said “ah” since 2 weeks old

Tried to hold her own bottle at 3 1/2 weeks

Rolled over from her stomach at 3 weeks and keeps her head up the entire time during tummy time

She has supported her own weight at 3 weeks old with little help (we hold her under her arms while she stands)

Moves her head from one side to the other (follows you) since 4 weeks

Is able to differentiate between voices since 2 weeks
