I have seen small and/or disabled children do this often. There was once a very impaired little girl in our parish (she had been severely abused when a baby). Her adoptive family brought her to every Mass and during the Consecration, she would always get this brilliant smile on her face and reach toward the Eucharist with both hands and arms. Most of the parishioners believed that she truly saw Jesus in those moments.
Fantastice, and I suspect REAL accounts.
Blessings.
