I used Graham’s Natural eczema cream and it seemed to help more than the other brands.

Aveeno dermexa or a script for something stronger?

See ur GP dr. Recommend you such creams which is good for eczema

QV? I’d go see a doctor to help clear it up poor bub.

Chlorine could be what’s drying his skin. Seek to advice if mild steroid is needed

Frankly Eco – Baby bum cream

I found that MooGoo eczema & psoriasis cream worked best for my baby boy!

ego QV is good and Goats milk products. Good luck.

I would def. stop swimming. if dermeze isn’t working its the pool

Does it flare up after swimming? Pawpaw cream or ungvita oil.

It could be the chemicals in the pool. You could stop lessons and see if it improves.
Another thing that could be causing is the clothing he is wearing. A lot of synthetic fabrics can cause eczema. See if you can get 100% Cotton clothing for him or at least put him in cotton singlets or t-shirts under his other clothes. Cotton blend is better then straight synthetic.I know a little girl that parents had to do that. Most synthetic fabrics don’t “breathe”. It often causes baby to perspire more even if his skin feels cold. Make sure your baby doesn’t get too warm/ hot as that can cause eczema for some. Not just for babies but for older children…..and adults.
I suggest you speak to your pharmacist and ask for other suggestions. If it gets too bad I suggest you take him to the Dr. who may be able to recommend something. I know one child who suddenly had a very bad reaction to one nappy cream, so bad that she rushed her to the local country hospital as it was after hours – no after hours locum service where they live. The Dr. came in, took one look at it and told us that she had seen that problem before, She gave her a prescription for one that she knew would heal the problem and to use in future…..and some to use overnight,
