My cousin and I are in an unspoken competition with our kids lol my son and her daughter were born days apart. We're always trying to one up each other with the milestones but she said she's introduced her daughter to water and juice already but I haven't. What's the rush for that? My son still spits out foreign liquids/foods (anything not formula) so he's not ready but what's the purpose in introducing these things at 5 months old?
