In all honesty, alot of things these days are really good marketing gimmicks.

Long sleeve bodysuits for winter are definite for under wondersuits/onesies.

As long as you have the basics like nappies, wipes, spew rags (flannel nappies I used too - and still am for my third!!) - everything else can be bought as needed - because sometimes you just dont need it! A brush and comb - meh - not necessary - I do have safety nail clippers which are good now that my 4yo and 6yo want to cut their own(!) - but newborn you chew with your teeth, you dont cut them anyway.

Medicine dispenser(?) - do you mean that hollow spoon shaped thing? dont need it hun - all medications comes with droppers that are much easier to use with the little ones.

Pawpaw ointment is a must in my opinion
