Beverage or supplement tips please

Hello! Si LO is 23mons old. BF kami eversince. Ayaw nya uminom ng milk madami na po ako natry, pero tinitikman lang nya then pag pinilit namin sumusuka sya. Okay lang ba kung choco flavor nalang ioffer ko? Or baka may marecommend kayo na pwedeng beverage at the same healthy din. Im afraid na maging hyper sya kapag nag choco drink sya. 😔 #advicepls
