HI! Been there, done that! :)
I have two boys who are now 11 and 9. (2 years apart, just like you.)
We had our first son completely potty trained before he was even two..... but...... then we brought home this new baby with DIAPERS. So our oldest son completely regressed. This was so frustrating, because we knew he knew how. A YEAR AND A HALF LATER (after trying everything under the sun), we completely dropped it. We told him that he was a big boy, but if he likes Pull Ups, that was fine with us, and that whenever he was ready, to just let us know, and we would help him. And we meant it! We were so tired of fighting and worrying about what everyone thought. Because (I'm sure you already know this yourself) EVERYONE has something to say about it. (Especially IN-LAWS!)
Anyhow, he almost immediately started using the potty again. THANK GOD!!! They are at that independent age where they want to be in control of everything. And using the potty is completely in their control. And on top of their age issues, they also have this new "competitor" in the house who seems to be getting all of the attention. And I'm sure you have heard this too, but even bad attention is good enough for a toddler.
Whenever it was time to potty train our second son, we never really tried. When he turned two, we told him that he was old enough to use the potty now, and that whenever he was ready, just let us know and we would help him. He wasn't interested for about six months, but only had about three accidents when HE decided to learn. It was completely stress free, and he is a much more confident child than our first, and I truly believe the whole potty training experience had a lot to do with it.
Good luck! It really does get a lot easier!!! You are very close to a great turning point! Mine are best friends now!
