This is all totally normal. It doesn't necessarily end, either...but takes different forms as baby gets older and more able to do more things! What's important is to not get mad at your babe, to not become coercive, force a position, try a rewards system, or overly praise when you get what *you* want. Your baby is just telling you that she's PART of this process now...this is new for her...and she is also experimenting with when and where she goes, and how often.
My suggestion is to continue to *communicate*....EC is about that, after all. It's not defiance. It's her Communicating that she needs a change. She needs support in exploration, and she also needs information about when and where to go.
Also, the #1 thing to do with a 7 month old on "potty pause" is to try a different position, environment, cue, or receptacle. Eventually, she will want to go on the potty again b/c that's what YOU do. :)
Another view on a potty pause, which I love, is that it's just ^part of the process^. We don't stop letting our kids try to walk when they stumble and trip, do we? So, even if you put that diaper back on, do not give up! Just continue to communicate, matter-of-factly..."You don't want to go on your potty. Okay, let's try the sink. No? Okay, let's try outside. Still no? Okay, well, I'm gonna put your diaper back on and just let me know next time you need to go."
You may find that relying on Timing also goes out the window, as baby will begin to want more control (of course!)...esp at around 12 months, which is where we are! We are now encouraging baby to sit on the mini potty by talking about it more and finding a potty that HE wants to sit on. Stories, songs, and straight-forward conversation. :O)
Hope this helps!! Hang in there!!
