Water familiarisation and traumatisation at 3m

We’re currently attending a water wellness program that focuses on getting baby used to the water in the pool. It is a gentle introduction and is strictly no submersion. Although, there is a warning of “1, 2, under” and trickling some water down baby’s face.

My baby (13w) hated the first session and we got out in less than 10 minutes and then he tolerated the next lesson better and lasted the full session although he still cried. He was pretty wiped after both sessions and napped for 2-3 hours afterwards.

Despite not crying as much the following session, will continuing to expose him to the pool traumatise him because he’s still crying? Or will it help with familiarisation?

We’ve signed up for a parents and bubs aqua HITT class (parents work out, baby stays in a flotation device like little boat) two days in a row and a comment a friend has made about traumatising them if they don’t like it has made me worried. Is two days in a row too much as well?
