It is indeed time to stop your little son's nightly rooibos tea party. In any case tea will not fill him so he is not hungry and does not need this extra tea at night.

He will probably cry and perform about this but you need to be firm about stopping his 4 bottles of rooibos every night which is obviously interfering with your sleep and with your son's sleep as well.
