Now even more confused .. My 3 year old had both at around 12 and 15 months of age and my 14 months old had hers at 1 year of age and is due to have her booster in the next 1 or two months :/ it would be easier not to read the article till she had her second MMR They both were fine after their jabs ... There is another thing that comes to my mind in some places they say yr Kids get their MMT at the age of 1 then a booster around 15 months then another say 1 year, 15 months and again before going to reception and I even found one more saying they get when they 1 then a booster when they around 4 or 3 years and 5 months ;/ Think I will leave for a long while because after reading all these comments and articles I'm more confused and it's even more difficult to decide :/ Thank you all for yr opinions
