The additional mention of the red life jacket appears to confirm the original interpretation provided meaning that the boy is covered by the blood of Jesus- red for the Blood of Jesus. I believe the little boy is saved and you will need to play a crucial role in his life as already mentioned in the first interpretation. This may be someone you currently know or may come into your life. He may not be a literal small boy but there might be a BIG age gap in addition to the other possible options that I had already mentioned in my original interpretation. As always, please take everything that I share to the Holy Spirit as He Alone gives the accurate interpretation.
