What fruit should I avoid if baby (10 months old) is having cough and phlegm? Or rather, what fruit is ok to give? My mom said don't give banana and all citrus fruit. How about apples, avocado, pear, strawberry etc?

Citrus is definetly a nono. Babies and toods tunmies are too sensitive and vulnerable. Advocado is a good option it has all the nutritional value in it. Apples, pear, carrots are all good options. Also oats instead of rice :) Here is a link to help you out : https://www.google.com.sg/url?sa=t&source=web&rct=j&url=http://wholesomebabyfood.momtastic.com/solidfood10to12montholdbaby.htm&ved=0ahUKEwiBkraL7oTPAhXGLY8KHW7vCwIQFgghMAA&usg=AFQjCNEnQ6CYRUBorWjjys3YLBtU_Ah3EA&sig2=1ivThV3i2GupRxby8oy26w
