Do all mums need to be sleep deprived?

I was told that im not sleep deprived enough. I know she didn't mean to say it in a bad way but im just taken aback. Am i really selfish and ignorant to wanting better nights? LO is on mix feed. After 12MN we'll give her FM instead and i dont pump in the wee hours. I just want to function better in the morning but can't help to feel that im not doing enough. #1stimemom
