She visited with students, teachers and community members at the Willows Primary School in Manchester, England, on Tuesday, looking radiant as ever.
The 31-year-old, who helped launch a counseling program for kids, donned a floral-patterned dress that showed off her burgeoning baby bump more than ever:
Kate was accompanied by comedian John Bishop to kick off MPACT, Action on Addiction's counseling program for children with parents battling addiction.

"Through my Patronage of Action on Addiction, I feel fortunate to have met a wide range of inspirational people who have overcome addiction," she said.
"But those who are addicted are not the only victims… I have been struck by the profound and deeply damaging impact it has on the children of affected parents."
"My hope is that through this specialized and targeted delivery of care, these children will have the best possible start in life, the one that they deserve."
Once again, it's wonderful to see Kate Middleton doing her part to help those in need ... and looking wonderful as a pregnant person, we have to say.
