Waking up happy then sad the rest of the day :(

April

Hi all! So my daughter wakes up all smiles and is super smiley and contest for the first part of the day but after her first nap she’s pretty fussy the rest of the day except when she’s asleep is this a leap thing? She’s just not happy very long or often no matter what we do to play with her after her first nap. Maybe she isn’t getting enough sleep? The second I go to put her in her gym or boppy pillow or bouncer she screams idk what to do to help her 😔she used to always be so happy
