Thanks ladies for all your tips.
I decided enough was enough on Feb 15th and put Caleb in the training underpants after he got up from his nap/rest time. He had one accident with DH while Caleb was playing in the sink (good thing was it was in the bathroom so no cleaning on the rugs for DH). We did pull ups at night and rest time but underpants all waking hours. He has done great!! Once in a while he waits too long and goes a little before we make it to the potty but most times he makes it just fine. And a few times he has just gone all on his own (making him feel like such a big kid). We have done great with poop in the potty too (he always went poop in his pull ups and refused to go on the potty even though he would tell us when he started going in his pull up). We only had one poop not in the potty but he was still in his pull up after nap time. I am so excited that he is doing so well!! I am so happy to be done buying his diapers!! The added test will be traveling to see the in-laws this weekend (he has done good there in the past when he was on his potty using kick at Christmas). He has done good out shopping and at the park so we are hopeful!! Then for easter we are taking a long drive south to visit my family so that will be the final test I think. I have faith that he will do good....just the added stress of potty stops along the drives for me but it is well worth it!!
Again thank you for all your tips. Now to work on our 20 month old daughter and get her diaper free (by 2 would be nice but we will see how she does)
