Starting to move but forgetting to tell mama

Xamira • Love never decreases from being shared
Hi everyone! I have a five month old baby boy that's been pottie trained since birth but now that he's starting to discover the world and moving around the surface... he's forgetting to signal before peeing! I'm glad though that is just pee right now but it's been hard this couple of days to keep the carpet dry!
Any advices to follow on this stage?
