Not true. Solids are introduced at 6 months, according to the WHO guidelines.
Babies are very well looked after in their first couple of years, with lots of pediatrician visits, where you will be given lots of guidance. Each pediatrician might have a slightly personal take on the order of introducing certain foods, but nothing big.
I think what you heard might stem from the (english) mantra "Food is fun until they are one". Not sure what, if any, the Spanish equivalent is, but they certainly seem to expect that babies will continue to get most of their dietary needs from milk, with solid food being offered as an extra not an alternative around the year mark. This was our experience anyway: while the pediatrician always asked what food we were giving DD at her pre-12 months check up, it was only after DD turned 1 year that we really got grilled about her diet.
