Yeah I can’t recognize my own daughter in the first few weeks/months of her life even if I look at the pictures and know its her.
There was a case in my country where two babies were swapped at the hospital. One mom had the presence of mind to take pictures right after giving birth, which she used to prove that she was given the wrong baby (hers had a full head of hair). The other parents were blissfully ignorant of the fact there was a switch.
