First of all, I researched the heck out of potty training gear and am willing to pay for the most effective stuff. These are great super soft, great leg opening, thick and high quality, but honestly Gerber's (which are thinner) or Dimore (equally thick) have been more effective and better value for us (we have 2 yr boy). Since we need to wash and change often, having a dozen lined cute Walmart Gerber's for the same price of  3 Scotty's was a smarter purchase for us. When I put these on my son, he would pee unknowingly right through them. I switched to a thinner version, he immediately want to use his potty chair/toilet and mostly trained within a week. Every kid different, but these would work better later in potty training at least for a boy. If you don't mind paying more and prefer or need the thicker feel, these would work fine. I would still use these later when he's ready for night time training because they are very thick, but I don't see myself rushing to purchase more because the Dimore training pants which are more readily available and less expensive has an equivalent waterproof PUL outer layer, and cute designs (which I didn't realize was important, until my son pointed it out, yes even at 2 yrs!).
