how do you say
baby im sorry in spanish'''
encantado en conocerte glad to meet you
what does im pleased to meet you in spanish
yo siento = i regret/feel sorry for...
(yo) lo siento = i regret it/feel sorry for it.
without the lo, you leave the sentence hanging. sentir requires there to be some object of the regret or bad feeling. if you aren't specifying what that is, or it is understood in the context of the conversation, lo provides a sort of placeholder value for it.
May I ask why you would use lo siento and not yo siento'
lo siento mi amor
probably works best.
baby is bebe, but thats more like, an actual small child baby
