my little daughter is the same - Refuses to eat porridge !! Half a bowl is a good record for her la. She only takes 4 spoons (soup spoons) jar... she is almost 9 months !!
If you find a good solution, please let me know, too.
My son is the same when he first start to take solid food. He doesn't like watery food, but like to eat by himself with his finger. so I start to give him finger food around 8-9 months. After that he is happy. Now he is 1 and eat a lot better now.
Anyway, If he doesn't like porridge, you may try to give him baby cereals. There is no shot cut here, You just need A LOT of patient, and keep trying.
add oil ah.
