I own several pairs of L'il Baby Chaps and used them with two children. They are super comfy, easy, and wear well. You can use them with or without a cloth diaper tucked in. These really helped us get through the winter months when my dd was about 18 months old.
L'il Baby Chaps by EC Wear
Pros: warm, comfortable, easy for me
Cons: the larger toddler size was too large
I ordered a pair for my youngest (12 months at the time) and a pair for my oldest (2 and a half at the time). They were a little big for my youngest and way too big for my oldest. My oldest could have fit in the smaller ones but I was too cheap to buy another pair so I decided it was time for her to learn how to put on and off her own pants. Now it is winter again and I am so very happy that I have them. My youngest is now 19 months old and completely Diaper Free around the house. It was easy to make the transition this summer to full time DF and it has been just as easy to keep it this way even though it is freezing! On extra cold days, I put some leg warmers under the chaps with a longer jacket and she can go and play outside and squat in her "pee dirt" when she needs to go. She still isn't verbally communicating her potty needs but she really enjoys the freedom the pants allow her to have. I really wish I would have had a pair for my oldest for her first winter DF. She had a few set backs and potty pauses her first DF winter and so far, things have gone without a hitch with my youngest and her first DF winter. I strongly think it is because she is still able to maintain her indepence that she had this last spring and summer. It is just to much to ask of a small child to tell you when they need to go, take them to a bathroom, help them with their pants, all while holding their tiny little bladders. With the chaps, my daughter can walk to the nearest baby potty, climb on and go. At the most, she has to hold up a longer shirt. Easy peezy.
