Hi my 8 month old is on a fluid strike. He doesn't want milk or water. His wet nappies are getting lesser. What should I do?

How about giving him more soupy solids? Also agree on topping up with fruits for the time being . And try feeding him milk or water with spoon or sippy/straw Cup instead? Sometimes they love the novelty of drinking from something new. My nephew often doesn't want to drink his milk these days and our maid realized that putting him in the bouncer to drink milk is better than carrying him. Maybe you can try that? How much milk is he drinking now? There will be periods when baby will drink lesser milk but not to the extent totally reject fluids.
