It is normal for babies to go through phases where they seem to lose interest in toys, and there can be a variety of reasons for this. They may simply be more interested in exploring other things, such as their own hands and feet or the objects around them. It could also be that they are feeling under the weather, are going through a growth spurt, or are experiencing some other temporary change that is affecting their behavior. If you are concerned that your baby is not showing an interest in toys, you can try rotating their toys to keep them fresh and engaging, introducing new types of toys to see if they are more interested in those, or simply giving your baby some extra cuddles and attention. If the problem persists or if you have any other concerns about your baby's development, it is always a good idea to consult with a pediatrician.
