וChelek 6
- The order of Kiddush on the first night is first Hagoffen, then Kiddush Hayom, then Layshayv and after that Shehecheyanu. Shehecheyanu is last because it goes back on the Yom Tov and on the mitzva of Suka. Bedieved, if you said Shehecheyanu before Layshayv, do not repeat Shehecheyanu. (ShA – MB )
- On the second night, Shehecheyanu is not necessary for the sukka since you said it the night before – as stated above in siman 641 that a Shehecheyanu on the sukka can be recited before Sukos. This is not so for the Shehecheyanu on the Yom Tov – if the second day is the real Yom Tov, the blessing you said on the first night does not count. (BeH “v’acher kach”)
- Our minhag is to say Kiddush while sitting, especially when being motzi others. (Rama – BeH “l’haRaMBaM”)
- It is fitting to bless Layshayv out loud, drawing it out with a tune like the rest of Kiddush. Actually, this applies to all blessings – make a habit of saying them out loud because the voice arouses kavana. (MB )
- Our minhag during the week is to bless Layshayv after Hamotzi, before you taste the bread. On Shabbos and Yom Tov that have Kiddush, we say Layshayv after Kiddush. Both are for the same reason – once you enter into the meal, the main obligation of Suka starts and it’s time to say Layshayv. (ShA – MB , )
- Some poskim hold that for the morning Kiddush you shouldn’t say a Layshayv between Hagoffen and the drinking, rather wait and say Layshayv after Hamotzi. This way is also acceptable. But if you do not want to begin the bread meal now, you are just eating some cake – all agree to say a Layshayv before drinking the Kiddush wine. (MB )
