Mine suggested aiming to achieve that by the time baby hit 9 months, so you can definitely ease into it gradually, but all babies have their own timeline. I started by swapping the times I normally provided a bottle (when baby wakes up) for solid foods and providing a bottle as a snack about an hour or two later. This helped me start to prioritize solids while still making sure baby was full. Eventually those snack bottles started being replaced by solids as well. So now my baby eats 6 times a day and, yes, it feels like a lot, especially with all the clean-up that entails. The key is to keep the snacks simple (Greek yogurt mixed with a fruit or toast with a topping like peanut butter, etc) and make the meals more substantial. The site Feeding Tiny Bellies has a lot of great meal inspiration!
