LO is 12 months. At his 1yr well visit I asked and his doc said to start eliminating it in early summer (may?) and just be judicious about bottles before bed/teeth brushing. This sounds good because LO still doesn't drink consistently from a sippy (maybe half a sippy a day) but he will be around 15 months then. Is that too late ? I feel like most ppl take it away around 12 months ?
