ReGex: Get multiple Matches out of repeating sequence

I'm trying to split a multiline string in python using regex. My regex experience is limited.

The string has a structure like this:

asdf
foo 1
bar
barfoo
bar
foo 2
baz 
baz 
...
foo 20 
bat
bat

I'm looking for an expression that will find multiple matches, as currently I only find everything or nothing. So the output should be something like:

["foo 1\nbarbarfoobar","foo 2 \nbaz\nbaz\n...",...]

As I understand it, I should look for a foo \d+ followed by some random stuff... ((\n|.*)?)*

foo \d+((\n|.*)?)*

I've researched about negative lookaheads, but inserting one did not help me.

foo \d+((\n|.*)?)*(?!foo)

I guess this could be solved by using only the built-in String methods, but later on I'll have to do things like this alot, so I'm looking for a "simple" solution.

([\s\S]+?(?=(?:\nfoo \d+|$)))

You can try this with re.findall.See demo.
