What should I do if my toddler rejects textures like roti or paratha?

It is common for toddlers to go through phases of rejecting specific textures. Continue to offer the food in rotation without pressure, as frequent, low-stress exposure is the best way to encourage acceptance. You might have better luck by varying the size of the pieces, offering them separately from other foods, or using a cookie cutter to make "mini" versions that give the child more independence while eating.
