My son's foreskin has gotten a bit irritated and red before. If it's actually pus coming out rather than a bit of curdy, white debris (which can look like pus) then it's infected. I'd put some non-irritating topical ointment on it, like lanolin and if it really looks infected then maybe some antibiotic first like bactroban, then a barrier cream like lanolin.

A UTI wouldn't have pus come out, the infection's so far up in the bladder that it doesn't do that, and boys rarely get uti's... but if the foreskin is infected or irritated then it'll produce pus.

I'd also cut out any irritant like bubble baths or harsh soap that come in contact with his penis. I wound up taking my son to the doc and got a prescription for antibiotics but i never needed to fill it coz it started getting better that day with lanolin alone (it was just red from irritation rather than bacterial infection).

have you allowed his foreskin to retract naturally? is it possible that it was forcibly retracted, either by accident or by his own doing? asking him if it hurts & when it began hurting will give you a clearer idea of what you're facing. everyone's advice on herbal soaks & topical solutions sound great. my boy's foreskin is still very much attached, as he's only 21 months old, but it sometimes looks a little red & inflamed, so i will take this advice too.

With all due respect for the alternative treatments, I'd make an appointment for the MD in a case like this.
Poor lil' guy. I hope he feels better soon.

In my experience with my son (he's 6.5 now...) he started to retract his foreskin on his own between 4 and 5... no one should ever force it back (tho MD's will unwisely tell you to do so)... full retraction can occur in between the ages of 3-4 to 12-14... rising testosterone levels in puberty usually allow any remaining adhesions to release... again, as long as the urethra is no blocked, there is no problem... these things take time for a reason... the foreskin is helping protect a very delicate organ...

Pus, however, is never natural, no mater how much or how little presents its self... this is a sign of infection and due to the delicate nature of this tissue should be dealt with as soon and as comfortably as possible... my son has had the red and itchy moments, usually due to lack of proper hygiene... a good hot bath usually does the trick... I've never had to become invasive with any cleaning procedures or going to the doc's...

Teaching my young boy how to help keep himself clean turned out to be helpful and important... (this is why we do need to wash our hands!! My boy needs that reminder daily!) He now knows that if his penis is bothering him, it's because it needs to be washed... he usually comes to me if he's concerned, and we've had no major problems yet...

Jessica suggested using lanolin, to help keep the area clean and relieve the tissue... this, I think, will help greatly... the barrier of lanolin would also help prevent adhesions forming as a result of infection, depending of course on whether or not this was due to any forced retraction... If his foreskin retracts on it's own, then it's fine... but if you are ever forcing it, you will know the difference! And your son will let you know!

Much luck to you Mama...!!

For regular washing protocol, I just showed my son how to use a washcloth
and wash around down there...
your son will run up to you some day soon and say "look what I can do!!"
and his foreskin will be retracting... that's when
you just show him to wash while the skin is retracted... that simple...

running around naked is fun for them, and so wash time can be too!!
