It almost sounds like the tank is not (or has not cycled). The numbers to some extent make some sense. On 2/19 before your water change the ammonia number was 1.0, then you did a 50% change which would halve that number to 50% , which is what you report on 2/21. Is the nitrite moving at all? When you post the numbers can you post all 3 Ammonia/Nitrite/Nitrate?
What all is in the tank? gravel? you said plant(s)..live? anything else?
You're not cleaning the lid, or glass or anything else with any cleaner are you?
I think you said the tank was for your child. Any chance that he/she may be sticking their hand or anything else in the tank to 'play with the fishy'?
