Baby bath/ lotion ect. Questions

So i have received a Johnson's take along kit, J. R. Watkins baby lotion and baby wash. Along with a tender times baby sample pack(17 years old- wont use it).

So my first question is if there are no alergies to the johnson or watkins can i use one then the other after the products are used up? Or will that cause irritation and or allergies?

How easy can you find Watkins baby stuff in stores? I love the products my self but there is no longer a supplier in my area.

And finally is tender times still made? I cant find the company online but the products i received look like really good natural options.

Any other brand recommendations??
