Puppy growth spurts and eating habits...?

[Abby&Fiona]

I have a question about puppy growth and eating habits.
Last week our puppy (possible american bulldog/mastiff mix) ate like a PIG and hardly napped!!! The last couple days she is eating WAY less but sleeping WAY more.....
Is this normal?? I just thought it was interesting how one day she was a PIG and another she was a lump on a log. haha
She is 12 weeks and 21lbs!
:-D
P.S. We also have an EM, that is why I am here

I know they all grow at different rates...curious what's next.

Mine does the same, her eating is up and down through the growth spurts. Usually her eating slows for a day or two then improves.

Yeah I notice that when there growing they will sleep more
