The former TOWIE star looked fabulous in her vibrant orange top and dark skinny jeans while browsing the stalls with her mum at the NEC on 13 May.
Among the goods she picked up was a book on helping babies sleep and a pregnancy pillow.
The former reality star - who is nearly 22 weeks along - later said: "What a great day at the baby show with mum @TheBabyShow highly recommended."
Maria is expecting her first child with BMX racer partner Kelvin Batey and has already revealed it will be a little girl. She spent the weekend getting space ready for her daughter's nursery.

She also reflected on how life has changed this year, quipping: "In bed before 9 on a Saturday. How life changes, wouldn't change it for the world. Time to oil my bump and download a new Kindle book."
