“You are conquering your daily challenges, and I’m here to hold your hand, when your dealing with sensory overload, the quietest room sounds like a big brass band.

“You excel in mathematics and amateur dramatics and you amaze me every day, because you are beautiful inside and out in an extra special way.

“The meltdowns, the routines and all the planning ahead.

“The groundhog days, the beige food and the temperamental ‘time for bed’.

“I love you unconditionally and will encourage you both to embrace your autism. Because you are totally unique and fantastically awesome.

“All my love always, mummy.”

The post was captioned “My babies, My world”. Christine added the hashtags “#Autism #AutismAwareness”.

Paddy, 43, and Christine are also parents to daughter Felicity, who was born in September.
