Feeding question.

Hello mum’s, I want to know how many and how much meals a 9 month old should had and what should be the gap between solids and milk. My son is 9 month old and least interested in eating I am struggling to give him solids he is so much disinterested in purées finger food or anything and also he is drinking milk in breaks like at once he will drin 2-3 oz so I have to give milk frequently. Say if I give him 180ml 6oz milk he will take 2-3 hrs to finish it so after that when she’s I give solid food. His eating is making me very stressed all the time.

Sorry for long post but m just looking for any suggestions may be I am doing something wrong. Which I can correct by you suggestions.
