teething baby

my little is currently 4 months an she’s starting to get to the point where she’s having off days (cranky, not wanting to eat normal, and sleeping lots more) any recommendations on how to get her to finish her bottles? i’ve tried giving them to her room temperature which she did better with but took WAY longer to get her to eat n she kept trying to just go to sleep while feeding…

she’s doing wonderful with her weight (15 pounds) n height (25 inches long) an i want her to continue to grow and gain, not backtrack!!!!
