I'm sorry, but I'm not surprised you've had a bad reaction to this product. As far as I can see, only 2 of its ingredients are not likely to have a bad effect (from irritation to cancer!).
A quick search of the ingredients contained in Johnson's bedtime bubble bath shows the following (from a variety of sources):

Polysorbate 20, Polysorbate-20 is fragrance component, a surfactant, an emulsifying agent, and a solubilizing agent.
Why is it a risk?
Polysorbate starts out as harmless sorbitol, but then it's treated with carcinogenic ethylene oxide. It's called Polysorbate 20 because it's treated with 20 "parts" of ethylene oxide. The higher the number, the more ethylene oxide it has been treated with. This substance is then combined with various fatty acids. The Skin Deep Database rates it as only a "one," and doesn't pick up on the risk that it could be contaminated with ethylene oxide, and subsequently, 1,4 dioxane. In addition, it can be laced with heavy metals.

PEG-150 Distearate, The Cosmetics Database finds PEG 150 Distearate to be a moderate hazard depending on usage and notes contamination and toxicity concerns.
According to a study published in the International Journal of Toxicology, PEG 150 Distearate can contain harmful impurities, including: Ethylene Oxide, known to increase the incidences of uterine and breast cancers and of leukemia and brain cancer, according to experimental results reported by the National Toxicology Program; 1,4-dioxane, a known carcinogen; PAHs, known to increase the risk of breast cancer; lead; iron; and arsenic (Source).
Tetrasodium EDTA, The Cosmetics Database considers Tetrasodium EDTA a low to moderate hazard ingredient, depending on its usage. It notes concerns regarding cancer, enhanced skin absorption, organ system toxicity and irritation (due to animal studies that showed skin irritation at low doses). It is classified as a high human health priority and expected to be toxic or harmful.

Personally, I would not be using this on my skin, nor on my childrens'.
Your skin is the body's largest organ. Anything you use on your skin can and will be absorbed by your body, and 'migrate' to other parts of your body (which is why such things as nicotene patches and ibuprofen gel work when applied to the skin). Incidences of cancers (of all kinds) have skyrocketted in recent years, as use of such ingredients as these has become more widespread.
It is therefore of vital importance, IMO, that we all use products that are as natural as possible, and research the ingredients we are putting on our skin instead of trusting that a huge corporation will have made sure it's safe just because they put 'baby' on the bottle!
