I don't think I'll ever manage to catch up on these threads so apologies if this is out of place but that swim float for the baby, we have the same one. My baby is the same age but we have the large size btw he's a very average sized baby maybe slightly on the smaller side so if she really did buy the small one she is a wasteful idiot (tell us something we don't know).
More importantly though I can't believe she let her go to sleep in there and left her in the pool taking photos. We used ours for the first time yesterday and as soon as my baby got grouchy he started trying to bob his head down toward the water (breastfed and searching for a nipple i think), so because I was watching him, closely watching him Lazy, I took him out of the seat and water, got him dressed, fed him and he had a nap safely in the pram.
She is such an idiot it hurts, not 1 care for their safety.
