A single drop-and-catch with the foot comes first, then one touch and catch, then two touches and catch, and only after that, continuous juggling, moving up a step only after three clean reps in a row. Telling a beginner to just keep it up for longer skips the step that comes before that entirely.

The mistake almost everyone makes
How to teach a child to juggle a football usually starts in the wrong place: jumping straight to continuous juggling skips the actual foundation underneath it. A true beginner needs a genuine first step below "try to keep it up", something small enough to succeed at on the very first go.
A numbered ladder, not a single skill
This four-step ladder breaks the whole skill into four small, separate wins, each one a genuine step up from the last.
Drop and catch with the foot. Drop the ball from waist height, let it bounce once, then touch it lightly with the foot without trying to lift it, just feeling the contact, before catching it in both hands.
One touch, then catch. Drop, one foot-touch upward, catch.
Two touches, then catch. Drop, two touches upward, catch.
Continuous. No catching. This is the first time it should ever be attempted, not the starting point.
A rule most advice never states
A keepy uppy progression for beginners needs a clear rule for when to move on, and a single clear rule most competing content never states works well: three clean reps in a row at one step before moving to the next.
Drop back a step without any fuss if a step that was working starts falling apart. Progress is not always a straight line for a beginner, and treating a wobble as a reason to step back, not a failure, keeps the whole ladder feeling manageable.

Honest troubleshooting
Two stalls come up more than any others. The ball spinning away sideways is usually the foot meeting it off-centre, not underneath, so slowing the drop right down and checking the contact point fixes it faster than repeating the same fast attempt.
Over-kicking on the second touch, sending it too high to control, is usually solved by aiming for a smaller lift rather than a bigger one. A touch that barely clears the foot beats one that sends the ball out of easy reach.
Quick answers
A simple drop and catch with the foot: drop the ball from waist height, let it bounce once, then touch it lightly with the foot without lifting it, and catch it back in both hands.
Three clean reps in a row at the current step is a reasonable rule before moving up, and it is fine to drop back a step if a step that was working starts falling apart.
Almost always the foot is meeting the ball slightly off-centre rather than underneath it. Slow the drop down and check the contact point before adding speed back.
Keep going
