Sami, that's great news that you have had even more reassurance.
WRT day care, if they won't let your DS have the toddler food, then you can always send your own food and tell them to feed him that instead. Also, don't worry about a bottle. Neither of my boys drank from a bottle but happily drank EBM from a sippy cup at day care. They were both able to drink from sippy cups from around 3 or 4 months, and I introduced straw cups not much later. So there are some options for you. And even if you don't have much luck at home, they are more likely to drink when they are thirsty and you're not there. So don't worry hun.
