Paul Davies was jailed for 20 months after he admitted causing grievous bodily harm to the infant . A former soldier who battered a seven-month-old baby so badly that its eyes rolled to the back of its head has been jailed . Paul Davies , 28 , left the infant with life-changing injuries and then falsely claimed to the child 's mother that it had suffered a seizure . The woman said she had trusted Davies to look after the seven-month-old and when she returned he claimed the baby had 'gone rigid ' after having some milk and vomiting . Prosecuting , Tara Wolfe said : 'He said he started to become panicky . He said he tried to call 999 but his phone was n't working . ' The baby was 'pale and stiff ' when paramedics arrived and rushed it to hospital where scans found bruising around the neck , a brain bleed and bleeding to both retinas . Experts told the court the brain injuries were most probably due to shaking , and that the full effects of the trauma may not be known for years . The victim 's mother , who is also not being identified , told the court she had 'trusted ' Davis with the baby . Davis , of Clevedon , Somerset , initially denied injuring the tot and implied it could have been forcefully treated by its mother or paramedics . But he pleaded guilty to causing grievous bodily harm to the infant and was jailed for a 20 months at Bristol Crown Court . Judge Michael Roach told him : 'We will never know precisely how the baby came by its injuries . 'Whether through temper or loss of control , you caused devastating injuries to that small child . ' Defending , Fiona Elder said : 'It was a one-off incident and a momentary loss of control . ' She said Davis had been using his former partner 's phone and the day before the incident she had cancelled her contract and left him unable to call 999 . The court heard Davis was medically discharged from the Army and was suffering from post-traumatic stress disorder . At Bristol Crown Court , pictured , Judge Michael Roach said Davies had caused 'devastating ' injuries to the child .
