Ack, it's so hard to give it like that for the little ones. I know you're supposed to, but when Max was 3 months old he was eating every 2 hrs, waking up starving (so no holding him off).
Hope the reditabs work for you.
If you do switch, you have two options. You could do the powdered, which you mix at your dosage when you want and only have to go to the pharmacy once a month. It is kinda a pain to administer but it gets easier with practice. Or you can do a suspension, if your insurance will pay for it, but you have to get it weekly because it expires within a certain days of mixing it. Much easier to administer, just a PITA if your only compounding pharmacy isn't convenient.
