Skipping a day’s meals

Lala

Just as LO’s appetite is back up, she started drooling again and lost her appetite again. In the past, when teething she’ll eat but not much but the past few days she seems to be eating less than usual teething period. Yesterday, she barely ate any of her 3 meals and only ate her fruits snack, dry teething cracker and milk. should i be worried or is this normal for a one yo who’s teething? Does your LO ever skip a day/more meals?
