My 17 week old has had a major loss of appetite last few days.. only time we can get her to eat the usual amount of oz (4.5) is when she’s half asleep.. which isn’t often because she fights sleep like the devil. other than that she will only eat about 2 or get super pissed and fuss when we’re trying to feed her. Every now and then she will fuss for a while then eventually eat so so far she has been getting close to the normal amount of a day but still less than usual. She’s bottle fed and no changes to her formula or anything. Could it be teething ? I worry about her getting dehydrated.
