tmi poop, not mine lol

Is this normal 5-6 month poop?? She had an ear infection and along with it a lot of diarrhea, around the end of November I think and they put her on antibiotics. She got better and she's been off of it for awhile now but at her check up a couple of weeks ago I asked the doctor when he diarrhea would stop and he said when the antibiotics leave her system but it's been well over a month now and she STILL has it, is that diarrhea or did her poop change and that's how it's supposed to be ? Obviously ftm and don't know what an older baby's poop is like lol she eats food but not so much, maybe once a week. We haven't really gotten that into food yet, just BF.. the doctor said it was nothing to worry about unless she's fussier , not eating well and dehydrated. She was fine up until last night that I tried getting her to bed and she was so fussy and squirmy I was getting frustrated, then I stood her up for a little and she pushed so hard and a loud fart came out and along with it a lot of poop. Is there anything I can give her ? A juice ? She has her 6 month check up in a couple of days I just don't know if I should take her I earlier
