A close family friend said
last night: "Kate and Gerry love watching the twins grow up
but this is going to be difficult, a painful reminder of the
last time they saw Madeleine.
"Amelie looks so like
Madeleine did at her age although she has blonder hair. Even
Amelie says: 'I'm pretty, just like Madeleine!' It makes
Kate very tearful at times.
"Amelie loves swimming and
dressing like her sister - and still carries around her
sister's Cuddle Cat toy as if it were her own."
The kids' party is expected
to be held at the family home Rothley, Leics, on Sunday - a
full 20 months since Gerry and Kate, both 40, last saw
Maddie.
She vanished during a holiday
in Praia da Luz, sparking a global search. The couple still
believe she is alive. Her gran Eileen McCann, 68, said:
"It's the twins' big day and they're very excited. As hard
as it is, life has to go on."
Spokesman Clarence Mitchell
said: "The party is a very private occasion. Kate and Gerry
are busy working hard on the search for Madeleine."
