'Serious concerns' for missing baby and mum last seen five days ago

Police are concerned that a missing Ipswich woman doesn't have items such as food and clothing to care for her 18-month-old daughter.

Tara Inglis, 27, was last seen pushing her toddler in a pink pram on Tuesday afternoon near an intersection in Booval, west of Brisbane.

Police believe Ms Inglis and her daughter, along with a man known to her, were at the Booval Fair Shopping Centre around the same time.

The man has since been spoken to by police.

Detectives are now attempting to confirm Ms Inglis's movements last Tuesday and are urging anyone who may know her whereabouts to contact them.

It's understood Ms Inglis and her daughter both have medical conditions and there are concerns she doesn't have food or clothing for either herself or her daughter.

Ms Inglis is described as approximately 150cm tall with a very slim build and short, dyed red hair and was last seen wearing a blue T-shirt, shorts and thongs.
