Yes, yes, yes to the sleep!
Also - enjoy eating meals in a leisurely manner, uninterrupted and still hot.
Solo shopping without feeding times, pooey nappies or whiny toddlers to think about.
Have conversations with people - on the phone, face to face, whatever... enjoy being able to talk without crying (early stages) or someone calling "Mummy Mummy MUMMMMMMY" the second you pick pick up the phone.
Shower or bathe whenever you like and for however long you want. The put on clean clothes knowing they will probably stay clean and not be puked or pooed on
Enjoy the serenity
