You can use the "angel wing fold" and secure on baby with a snappi. This is a great solution for smaller babies, who still have very liquid poo, since it helps keep everything contained. You will need to use a diaper cover on top.
For a very easy solution, just fold the trifold in thirds and use inside a cover or pocket. This gives you a very absorbent, yet trim, 6 layer insert that unfolds for quick drying.
The diaper reaches its full absorbency after a few washes.
