３月頭、京都に４泊５日してきました！
2歳0歳で新幹線に乗るのは初めて。長女が0歳だった頃に新幹線は那須への往復、東京→軽井沢→新潟→金沢→東京と６回乗ったことがあります。ただ子供が2人、かつ混雑するJR東海道線（特に東京ー新大阪間は混む）となるとまた勝手が違うもの。
今回も割とうまく行った点と反省点があるので、シェアします！
n early March, we stayed in Kyoto for 4 nights and 5 days!
It was my first time riding the Shinkansen with a 2-year-old and an infant. When my eldest was an infant, we rode the Shinkansen six times round trip to Nasu, Tokyo → Karuizawa → Niigata → Kanazawa → Tokyo. However, having two children, especially on the crowded JR Tokaido Line (especially between Tokyo and Shin-Osaka), presented its own challenges.
Sharing my learning and knowledge here as much as possible!
結論から簡単にいうと、号車選び、席選びが大事、そのための予約サイトが大事、です。
To put it simply, choosing the right car and seats is crucial, and having a reservation site for that purpose is also crucial.
