Aries 2756: Yes, it is assur to cut both the feet and the hands at the same time, as it is done for a mais. It is also a halacha that one should cut every other nail in sequence, as cutting all straight is done for a mais. As previously mentioned, we also don’t leave our feet facing the door, as we sleep, as this is the position a mais is put. Please tell your manucurist/pedicurist to cut every other nail. For instance, to start with the thumb, middle finger, pinky and then the forefinger and then ring finger. Also one should not cut their nails on Thursday, as they will regrow on Shabbos.
It is not bobba mainzes that we don’t dress a child with 2 people helping. It should only be one person dressing or helping another, as 2 people do a mais.
May we only share in many simachot with simcha!
