Initially
just one front leg presented: not a promising start as both need to come
out at the same time, followed by the head.
It is likely that
Caravelle would have brought the leg back in and tried again but as I was
present (and unlike in wildlife films) I lent a helping hand and gently
pushed it back in!
As this photo shows
my effort was rewarded by a successful follow up with both legs
The nose then begins to appear..
well positioned for smooth progress...
