Physically, your pup's system will not be mature enough to deliberately "hold" any eliminations til 6 months or more. They'll understand sooner than they can fully comply so the idea is to get them out or on the pad, frequently, so they don't have the chance to make "mistakes".
The general guideline is that they can physically hold things for about one hour for about every month of age and will need to be taken out or to the pad
every morning directly after waking
after breakfast
after napping
after playing or exercise
after lunch
after playing or exercise
after napping
after dinner
after playing or exercise
after napping
just before going to bed
1-2 times thru the night
If you're not actively engaging with your pup, crating, expen or tethering will help you to help her be successful. By learning her "tell" when she needs to go will help. Keeping her in the correct size crate keeps her and the dwelling safe when you're not together. An expen gives her a bit more room where she can have a small crate, pee pad, safe toys, water, food, available.
I haven't looked at your previous posts so I just want to be sure that you know about hypoglycemia in toys and that you have a first aid kit and references put together since it sounds like getting help on an emergency basis could be tricky

. It sounds idyllic tho.
