my baby started eating veges at 5m. hes now 5m3w and eats a full jar, at 3 days into it he was eating half a jar. can i make him more? its just i make up the veges and his porridge and i freeze it in the jars, and i figure that the jars are that size for a reason. he could eat and eat if i let him. When did everyone else give baby more
