If a priest were baptizing a baby, and during the pronouncement of the form, attempted to pour water on the baby’s head, but because of the shape of the pouring vessel, the water only hit/flowed upon the baby’s head during the first cross (ie., in nomine patris...), but during the third cross, and possibly also during the second, the water instead of pouring out, merely ran down the side of the dish, clearly missing the baby, but from the priests angle, looked like it was pouring onto the baby, even though it wasn’t.
Would this be a valid baptism?
Doubtful or certain?
If I did a conditional baptism myself, would I sin?
