Question: i have an 18 month old approx 23 lbs and are going on vacation where there are many pools, would this be ideal for age and weight?
Document: Our pool only allows US Coast Guard certified flotation devices (even inflatable arm floaties are banned). After one too many slips and dunks in the baby pool, I did some research online and came across this product and decided to try it out with our 18 month old (~30 lbs).I am amazed by this flotation device. It took my daughter only a minute to get used to the floatie once in the water.
We bought this for my daughter who is 15 months old and weighs 26 lbs. We knew that it started for 30 lbs, but figured if it didn't work now, it would later. So anyways, we brought it as a second life jacket on our vacation to Wisconsin. We tried it on her and she loved wearing it around the house, the boat and then came the water...SHE LOVED IT! And it held her up amazingly well for being a little bit below the weight limit.
I purchase this for a 18 month old. he is now four and using it. It is getting snug around but still usable. Only complaint would be the straps in the back be made longer for broad chested boys who are still in the weight class. It still looks great after the seasons of wear. Highly recommend this for any little one.
I think this "life jacket" is good for a child who has some swimming abilities. We bought this for our 18 month old son and it did not keep him upright in the water on its own. We had to put an additional innertube type contraption also on him while in the water with him or else he would go under by either going sideways or backwards. After much thought, I am not sure what benefit this is over a regular standard life jacket.
I want to start by saying I think this product is really good & if your child fits in it then it is a great item & for many reasons you won't find anything better. Water safety is so important & from all of the reviews & the one I purchased this item seems to be of very good quality. My low rating would come in how it fits. The weight shows 30-50 lbs, but there is no way this is accurate.
Great product. I had one for my 2 year-old. She's now 5 and swims like a fish. Bought this one for her 23-month sister. Of course, at that age, she needs a little help and i wouldnt leave her unattended with it, but it allows her to float and somewhat swim without fear. Love it!
My daughter want to stay in water for hours and don't like anyone holding her or having some flotation tube while she is in the pool. She likes this and able to float without anyone's help now. I am also staying away from her since she is able to manage herself. When she make wild moves, it puts her in trouble for few seconds and then becomes normal.My daughter is 23 months old and 23 lbs. With my experience this will be suitable for 18+ months.
I bought two of these for my 23 month old and 3 year old daughters to use for a beach vacation. The three year olf was a newly independent swimmer and the 23 month old unable to swim at all by herself. These floats worked wonderfully. Both girls were able to swim by themselves and even jump in the pool without any assistance (other than close adult supervision). We used them in the ocean and it made for a much safer experience. The girls loved them.
My son was in the Coast Guard. We love that this product is Coast Guard approved. At a water park, my grandson-- age 23 months-- used this item instead of the park's life jackets. He swims/paddles around in our condo pool with his head held high above the water. He is barely 30 lbs and it fits just fine. He likes to wear his turtle.
Our 18 month old daughter loves this thing!We bought it when she was a little less than an year old and starting 'daddy and me' swim class. She hated it then, so we put it in the closet and took it back out a few months later. After seeing it a few times, with plenty of time in pools and the ocean, she started to be ok with it being there and even started wearing it for a minute or two.
