My tiny used to have the BEST sleep schedule and don't even think you could ruin it.... Now we are getting teeth in (pretty much since the beginning multiple at a time *currently either 4or6?*) but with this she does sleep as well as she used to & now wants to nurse to settle down & fall back to sleep *she does eat solid foods - I still nurse naps & comfort settle as a top off*.... I need her to have a better schedule & to sleep better, I'm tired again lol
