The former Spice Girl has decided that, after bottle-feeding her three boys, Brooklyn, 12, Romeo, eight, and Cruz, six, she wants to feed her fourth child naturally when she arrives this week.
Sources close to the 37-year-old said she was planning on opting for the 'Earth mother' approach.
According to British newspaper the Daily Mirror, Posh Spice told a friend: 'I'm doing everything differently this time. I want it all to be natural and perfect for my little girl.
'I'm so proud to be pregnant and I feel so blessed and so happy.'
