Erin McGregor is celebrating a special family moment

Erin has always been open and honest about Harry, who has autism, which means a great deal to her followers.

The mum's honesty and willingness to share the tough times and milestone moments helps a lot to parents in similar situations.

Erin said her son Harry has been struggling to get into the Halloween spirit and didn't enjoy his class party as much as she hoped.

However, things changed for the better on Halloween night when Harry embraced Halloween and surprised his mum.

"Harry struggled to get into the spirit during his class party ahead of the bank holiday," Erin explained.

The mum was so surprised by her son when he put makeup on and even let Erin spray his hair to complete his Joker costume.

She wrote on Instagram: "No I can’t deal with Mr Harry. This is huge like huge.

"He let me put makeup on and spray his hair. He even got around the block and used his word "ah"when saying trick or treat," Erin revealed.

She thanked her followers for being so supportive through everything this year.

She gushed: "Thank you so much everyone for all the love for this year. The fact he wanted to go out and treat or trick was a big step.

"This year was definitely a milestone. I could chat to him all day," the proud mum said.

Her followers praised her after she shared the heartwarming video of her and Harry on Halloween.

"I’ve tears watching this, just amazing," one said.
