From memory 3 milk feeds until 12 months is normal and because of the nutritional value it's definitely worth keeping them.
If it was me I'd probably drop the morning snack, move Lunch to 11.30 and have an afternoon snack
as he's hungry for dinner before your preferred time.
Really there is no wrong way to do it, it's down to balance of family needs and baby interests as to what you do. It certainly won't make long term difference to his eating as I had 2 completely different patterns with my 2 and the more 'standard' routine child is actually less of a good eater now he is older.
