I've got 4 boys. Age 14, twins age 6 and a baby 6 mths. Older 3 are fine. Before I give them their dinner I drink a shake so I'm not tempered.
With regard to feeding baby Aaron I do touch his food off my top lip. I've lost 2 stone in 6 weeks so I assume that is okay. As regard juice I measure it, supposed to be 1 part juice to 4 parts water but I add a little extra water, juice lasts longer, I save money and it's healthier for them lol.
For the baby I don't buy special baby juice such a waste of money. I barely colour the water with a few drops of unsweetened regular juice and he is happy with it so I don't need to taste it.
