I really feel you on this, it takes a lot of strength to be walking this journey and seeking help early is truly the best thing you can do for your little one. For therapy, it might be worth asking your PD for a referral to KKH or NUH as they have developmental paediatrics teams who can do a proper assessment and point you to the right early intervention programmes like EIPIC. On the milk formula side, I would check with his PD or a dietitian first before switching anything, since every child's needs are different and they can advise what suits him best. You are doing a great job by being so proactive, and this community is here with you every step of the way.
