Ready to go with room to grow! The Britax Poplar Convertible Car Seat takes the stress out of moving to the next car seat stage thanks to the patented ClickTight® Installation and slim SpaceSaver™ design. This car seat accommodates up to 50 pounds rear facing to help keep your child riding safely even longer and easily switches to a forward facing car seat as your child grows. ClickTight Technology installation provides fully open seat belt paths that are clearly labeled and easy to access, and the automatic tensioner takes care of the tightening. Slim outside and spacious inside, the toddler car seat features 17" SpaceSaver technology designed to fit 3-across* without compromising on trusted Britax safety and premium comfort. The Britax car seat boasts a patented SafeCell® crumple zone and V-shaped top tether to help manage crash energy. The reinforced frame and belt paths provide strength and stability. Rear facing car seat cover fabrics are naturally flame retardant with no added FR chemicals and safe to machine wash and dry. *Britax cannot guarantee 3-across installation fitment in all vehicles

Recommendation – Britax strongly recommends:

  • Children ride rear-facing to the highest weight or height specified
  • Children should remain in a child seat with a 5-point harness until reaching the maximum weight or height allowed
  • The top tether be used at ALL times when installing the child restraint forward-facing.

Preferred by daycare teachers!

Preferred by daycares because they open and close on the sides and kids can learn to pull on and take on on their own

Nice
Size: 3T-4T, Unit Count: 112
Good pull ups, it could get a little linty but it fits perfectly on my toddler. It stretches which I love. I do love how I could strap and unstrap the sides of the pull up. The designs on the pull up are cute. It holds a lot of pee and soaks it up very well. It’s comfortable on my toddler and the pee and poop doesn’t leak out of it. It is worth the money.

The Fast & the Curious- Potty Drift
Size: 5T-6T, Unit Count: 60
Who knew toddler potty training required both a PhD in fluid dynamics and Jedi mind tricks? These Pull-Ups prove the science part: leak-proof, absorbent, and surprisingly soft. The toddler-psychology part? That’s a battle of wills. Our little one was a die-hard fan of Huggies diapers—too loyal, in fact. We begged, we bribed, we pleaded: “Please, let’s move on!” Resistance was fierce. So we went stealth mode, sneaking Pull-Ups on at night like parents on a covert mission. Credit to mom—she cracked the code and finally got the kid interested in the toilet. Suddenly, the “potty rush” moments became less of a flood and more of a sprint. Diapers were too slow to peel off; Pull-Ups gave our little sprinter the speed boost they needed. They’re soft, rash-free, and practically leak-proof (unlike that other brand we don’t speak of). Pro tip: size up for easier toddler self-removal. The result? A drier, happier kid, less laundry for us, and the toilet finally earning MVP status. If you’re ready for your toddler to graduate from Diaper University, this is the diploma. Bonus: you’ll save money too.

Mom of 3 recommend!
Size: 5T-6T, Unit Count: 14
I'm using these again for the 3rd time and they're great as always. My 3rd is still having some issues at night time with bed wetting, and as they get older the bigger the mess, so these truly hold up to a full bladder. And they don't smell by morning like some diaper brands. I'm usually against pull ups, but these are great for up and down ease of use and that added protection when it comes to potty training. I love the bigger size inclusion for larger children which we struggle with for comfort compared to other brands.

Comfort and affordable
Size: Size 5, Unit Count: 56
⭐⭐⭐⭐⭐ Absolute Game Changer for Active Toddlers! If you have a little one who treats diaper changes like a wrestling match, you need the Pampers Cruisers 360. We switched a few months ago, and I honestly can’t imagine going back to traditional taped diapers. Here is why they are a staple in our household: * The "Gap-Free" Fit: The 360-degree stretchy waistband is genius. It fits snugly around the tummy and back, which has completely eliminated those dreaded "blowouts" during playtime or naps. * Easy On, Easy Off: Putting these on is as simple as pulling up a pair of pants. When it’s time for a change, you just tear the Easy-Tear Sides, roll it up, and use the built-in disposal tape. It makes mid-runway-escape changes actually possible. * Skin Friendly: My toddler has somewhat sensitive skin, but we’ve had zero issues with rashes. They are incredibly soft—almost like real underwear—and breathe really well. * Serious Absorbency: Even with a heavy wetter, these hold up overnight without leaks. The Dual Leak-Guard Barriers around the legs are the unsung heroes here. Bottom line: They are perfect for the "crawler-to-walker" transition. They stay in place no matter how much climbing or sprinting is happening. Definitely worth every penny for the peace of mind (and the saved outfits)!
