Little one constantly swallowing when waking up

Brook • Hadley 9-12-2019❤️❤️

She’s almost 1, in the last month or so when she is first waking up and sometimes randomly throughout the day she will start to constantly swallow and will take a deep breath in and continue doing it for a good 5-10 minutes, it kinda sounds like if you were going to puke and you keep swallowing to keep it down if that makes sense. Any ideas on what it could be? Or is it normal? She’s my only child so I’m not sure. We go to the doctors on the 17th for her one year check up so I’m going to bring it up then but if anyone has an idea of why she does it or if it’s totally normal let me know!
