My order didn’t arrive on time even though I paid premium delivery and my son had a swimming lesson so the instructor was kind enough to borrow us one for the class that day. We had a choice to choose a L or XL. I chose the XL only because the L was in pink (and I don’t like the colour pink).
It turns out that the XL was actually the perfect size for my son.
Therefore, I am returning the medium I bought for him because it was too small - it would have fit for when he was 0-2 weeks old but most definitely not now and he’s 5months.
I did like how snug the XL was around my son’s waist and thigh (it wasn’t too loose or tight).
Water Babies can do with adding more colours to the colour block designs. At the moment, it is only two (pink or blue) so more colours would have given me more choice.
Overall, based on the one provided by the instructor to be used just for the lesson, it is a lovely product . Perfect fit.
