When does life feel normal again

I got my 9 week old lab (Maggie) just over a week ago. Life feels super hectic. I knew it would, but I guess I need reassurance it calms down a bit. I have an 11 month old and a 4 year old. We have been crate training little pup and her crate is inside a play

Pen. This is primarily to encourage the crate to feel safe by choice at first but the play pen will come kinda redundant once she can jump over. The pen also stops little fingers getting into the crate when she is in there. I limit this time but I do rely on it quite a bit during the busier parts of the day, I feel so much guilt but she is well and truly in the shark phase and need to keep everyone safe. I feel like I’m juggling 10 balls from the minute I wake to the minute I go to bed. She can’t go out on walks yet as her round of vaccinations isn’t complete so we play in our small garden. If I need to split her from the kids from whatever reason I’ve started to open our back door and allow her to roam between the garden and kitchen with lots of toys. Any minute I get that isn’t mum duty I spend playing with and training her (we’ve got sit and lie down). We had a dog before Maggie, but we had no kids and all the time in the world apparently. She was also older, probably around 6 months but we weren’t sure. So when does it become “having a dog” and not “managing a feral puppy” – I guess is my question.
