Each parent is different I just said for me I wouldn't do it.
I understand a parent being finished before the toddler, I myself am over my 32 month old with his bad latch and my sore pregnancy nipples and trying to eat enough to sustain him and a twin pregnancy.
For my situation I'm weaning him gently by cutting down feed times and cutting down on the amount of feeds
Every parent needs to make the choice that is right for them. For me I wouldn't be comfortable using the approach of making it taste bad. Simple as that. No judgement. No statements claiming it's wrong. Just my personal stance.
