Question: Are these 0-30 or >30 life jackets? I have a tiny 6 month old (only about 14 lbs) and need a life jacket for him.
Document: This product I bought for my 4 month old for being out in the boat and around the lake. However she is small for her age this product does fit her. The padding does get in her mouth and she doesn't mind that. I had it on her for about 30 minutes and she didn't mind it to much. We will give it a full run for it's money this holiday week on Vacation and I will update. So the life vest works great. I tested her out in it in the water. I also found out that Kids under the age of 6 are supposed to have a life jacket with the pad around the neck area to hold the childs head above water.
We have now used this life jacket twice for our 8 month old son. It is very secure, and I really like the strap that goes in between his legs and snaps in the front. The other jackets we looked at did not have this feature, and I was worried about the jacket riding up on him. This one fit like a life jacket should, and when he was in the water it kept him upright. The strap on the top is helpful when picking him up out of the water and putting him on our boat.
Great life jacket! I'm using it for my 4 month old son who is 17 lbs and 26 inches long. When I put it on him I try to lay him down so he doesn't get lost in the fest. There's plenty of room for growth! He loves kicking around in it and it keeps his head up out of the water while he lays on his back! Just what we wanted to start him out in!
Ordered this life vest after reading the great reviews. My 18 month old is pretty tall for his age (usually 75th or 90th percentile) but weighs 25 pounds. Since he is less than 30 pounds I ordered the infant life vest over the childs vest. Safety is more important than comfort but this jacket is so tight it's to the point where I'm worried he can't breathe correctly. The vest is super tight on him and rides up to his chin. I feel as though I wasted my money on a life vest that doesn't fit.
We ordered this for our 6 month old grand son so he could enjoy some boat rids this summer. This is the perfect life jacket as it will keep him save in the water. It surrounds him with flotation material and is designed to keep his head well above the waterline. It will be big enough to fit him next year as well.
We were thrilled with this infant lifejacket. Good quality. Great price. It fits our 5 month old well. The padding on the front chest & behind the neck work great for keeping baby floating face up. Our daughter has a little room left but she's only 15 lbs now. I'm not sure if it will fit all the way up to 30 lbs and she's on the small side for her age.
I got this for my grandson and he is 6 months old weighing around 16 lbs and it is perfect for him! Very good quality! !
If your child is less than 30 pounds but tall for their age I suggest finding a better fitting life jacket.
We bought this for our 6 month old son on a trip to Traverse City so we could rent a sport boat and trust that our little guy could join us and be safe. We tested this jacket out at the community pool in advance, and let's just say that this thing works as-designed! Our son loves the water, so this was not a cruel test at all for him... but we dropped him in the water to see what would happen, and instantly he bobbed to the top, face-up, right on his back as-designed.
I bought this for my 6 month old, it fits perfectly. I plan on using it on our vacation in July. Quality seems to be very good, I cannot comment further until I use it.
