You are right, you could not do any better. Sometimes these things come all at once and ill explain why.
I think what's happening here is the ear infection triggered stress, which lowered the immune system. Once the immune system is compromised, it opens them up to all kinds of issues.
I would suggest adding a supplement like nuvet or hardypet to make sure your baby is getting all their nutrients. When the immune system is lowered, especially in combination with antibiotics or prescriptions, their vitamins get depleted very quickly.
Also add a smudge of plain yogurt once a day to make sure you are keeping the beneficial bacteria in the intestines. Antibiotics kill good and bad bacteria.
