Toddler approved
Size: 4T-5T, Unit Count: 99
Fits true to size and easy to pull up and down by my toddler. Very absorbent - perhaps a little too absorbent as it's taking my daughter forever to be potty trained and she's content in her soiled training pants... Great quality overall.

They prevent leaks, and fit great!
We have always used Huggies diapers for our babies and young toddlers because they were the only ones that never leaked or caused a rash. My second daughter was fully potty trained at 2.5 years old and never needed pull-ups. However, our third daughter, who also trained at 2.5 years old, digressed with her nighttime potty training due to instability - we moved twice within the first 6 weeks after she potty trained. So we had to get pull-ups for her to wear at night. Obviously since we loved Huggies diapers, we tried Huggies Pull-Ups, and again, they did not disappoint! They never leak, even on nights when she doesn't get up to go at all, and has lots of pee, and they have never caused a rash either, no matter how full. She's been using them for 1.5 years, at night, and we have never had any issues. They are dependable: decently comfortable to the child, do not cause rashes, fit properly with the ability to adjust at the thigh (if needed), and they prevent leaks! I highly recommend them!

Finally, a good night's sleep.
For almost a year, I've had sleep issues. No problem falling asleep, but I'd wake up 3 hours later and be up for the next 2-3 hours. I'd finally fall back asleep just a bit before the alarm and spend the rest of the day in a fog. It didn't matter whether I went to bed at 8:30 pm or 11pm - I was still up by 1:30-2 and awake for hours. It gradually got worse and I got desperate.
A friend recommended Melatonin and I resisted at first, having tried it after our daughter was born (almost 15 years ago). The tablets I took then had some odd side effects and I only took them for a few weeks before throwing the bottle away. Now, I think I have have been taking far too high of a dose, because these 3mg tablets work great.
Be careful when you take them! I'm awake and alert for about 20 minutes and then zone out totally - even in the middle of a conversation. After a couple of months, I've learned to just lay a tablet on my nightstand and take it when I'm ready to turn out the light. It works great: cured the problem of middle of the night sleeplessness. I still wake up sometimes at night, but have no trouble dropping back off to sleep. And when I wake up in the morning, I'm alert, energetic, and not already counting the hours until I can go back to bed to get a good night's sleep.
For me, this supplement would have been a good buy at twice the price - and my family agrees. I'm rested, cheerful, and so happy I gave it a try.
So far, no bad side effects. In fact, no side effects at all. I am taking it daily, but considering trying it on a more limited basis because of concerns about long-term effects. Considering, but haven't done it yet because I'm so enjoying a good night's sleep that I'm afraid to tinker with success!
Although I saw results the very first night I took this, I waited to write a review just in case it was a placebo effect at work. But it's been 11 weeks and I'm confident that this product is really effective for me.

Time release.. ONLY way to go
Used this brand before... when refill needed, came back for more. Time release is the best way to go as it works all night.
Not one big hit when you 1st go to sleep... A nice "hit"... to get you to sleep and then a slow release of the rest, to KEEP you asleep...
Don't think you'll be disappointed. I use sustained release with any vitamin/supplement I take (assuming the company makes it) .. including this. It's the best way to allow your body to utilize the product.
