Kate Middleton shows off growing baby bump as she displays thrifty side and rewears coat

Kate Middleton, 36, was out in London today, and the Duchess showed off her growing baby bump.

The mum-of-two was launching the pilot of a website aimed at giving primary school teachers practical resources to help support the mental health of their pupils.

Kate gave the green light to the initiative during a visit to a London primary school helping to trial the online portal coordinated and financed by the duchess’ Royal Foundation.

The free website for schools, called Mentally Healthy Schools, is expected to be available to primary’s nationwide in the spring after being monitored and reviewed.

Kate chose an entirely blue outfit for the appearance, perhaps hinting that she is expecting a baby boy in April.

The Sportmax coat, which she last wore on a visit to the Emma Bridgewater factory in 2015, featured large lapels which came down in a deep v, and Kate kept her neck covered with a scarf.

The Beulah London scarf, £95, was made up of a print of many blue shades to complement the coat.

She paired the coat, which is now sold out but originally cost $2490, with a pair of suede court shoes and blue sapphire drop earrings. Underneath the Duchess wore the Valerie maternity dress from Séraphine, £99.

The unusual earrings were in the shape of a small leaf, and featured delicate diamonds arround the sapphire centre.

Kate kept her makeup minimal for the day out, wearing lip balm and mascara but not much else.

Even her nails were plain, with the Duchess choosing not to wear any polish on her fingernails.

As usual, her hair was blow dried into a bouncy style which came down over her shoulders.

Her blue dress could be seen peeping out from underneath the Duchess’ coat when she bent down to speak to children at the school.

Kate has had a busy couple of weeks, visiting Wimbledon last week in a chic coat which she changed out of to put on a tracksuit.

The orange coat was from high street retailer Boden.

Kate appeared to wear a nude dress or skirt underneath the coat and added simple black heels to the look.
