Potty Training Continued. . .

I am such a proud mommy! Crew seems to be catching on to the toilet training and has actually done better being out of the house. I was so worried with our flight on Sunday and being in LA would mess everything up, but he surprised us without so much as an accident our whole day of travelling! And I'm glad to report that we are on day 4 of zero accidents! (during the day, we still working on the night time, he's about 50/50 right now)mommy just has to figure out how to keep the 'trigger' pointing down so he doesn't pee all over himself! That's been our only trouble these past few days. He tells me he needs to go we run to the toilet, I think it's pointing down and it ends up spraying the back of his shorts everytime! (just when we are out and about his toilet seat at home prevents all this mess) I'm so proud of my little guy who is now a BIG BOY as he likes to say "bi bow" any advice on the night time? I usually wake up and take him around 4 or 5am. He usually goes but last night he through a fit saying 'no mommy no poopoo no peepee! So I put him back in bed and 15mins later he peed. Is it bad to wake them in the wee hours to go? I'm afraid if I don't he'll have an accident and sleep in wet pjs all night. I guess I just don't know what's a reasonable number of hours a 2yr old is capable of holding it. Any advice would be great! Thanks!!!
