I've been EC my LO since 3months and had been doing fairly well until 7 month mark when she suddenly would not go in the toilet. I then started offering different places (ie the sink) which solved that issue. But now, at 9 months, she cries and want off the potty seat in the toilet, will not go in the sink but as soon as I set her on the bumbo.... She will go almost immediately. At first I thought this was a coincendence, but I tested it out today and we either had multiple misses in the bumbo or I successfully read her cues and she waited till i seated her in the bumbo before going. Help!! I don't know what to do!!!
