There are a number of signs to look for to see whether your baby is ready for weaning. These signs typically apply to any baby, whether they are weaning from a boob or bottle.
One sign that your baby may be ready to start solids is that they should be holding their head upright, independently and steadily, while seated for about fifteen minutes. (Do not attempt to feed your baby solids while they are lying down or in a reclined position as this can make it difficult for them to safely swallow.) Sitting up ensures they have good head and neck control, which are both necessary to safely eat solids, including more liquid “solids” like purées.
When your baby begins picking up objects and bringing them toward their mouth, this can be another sign that they are ready for solids. They may show an interest in food by watching you eat, mouthing for food, or leaning forward towards food. You may even notice your baby begin to reach for or grab food off your plate if you are holding them while eating! As cute as this is, take care not to give your baby access to any food that could pose a choking hazard. It’s important to start with soft foods in small pieces that don’t require teeth. Your baby should also always be closely supervised while eating, no matter how “safe” the food is.
One of the many reflexes your infant is born with includes a thrust reflex with their tongue. This reflex allows your baby to efficiently latch onto the breast or bottle while feeding. If you place your finger, a spoon, or anything near your baby’s mouth while they are newborns, their tongue will instinctively move outward, ready to latch. When you try to feed your baby solids before they are ready, their thrust reflex may push the food out of their mouth. As they grow and become ready to eat solid food, they will lose this reflex and you will know they are ready to begin solids.
