Different creams work for different children.
I also found that over time creams became less effective/ made worse.
Currently using epaderm. Bit like vaseline but very effective.
The most important thing/s to remeber are:
Keep skin as moisturised as possible, use emolient at least twice a day
Don't over bathe baby, as it dries the skin. Top and tail daily then bath 1 -2 times a week.
Steroid will only thin the skin if used excessively for prolonged periods.
If starting flare I always use for 2-3 days till clear then up the emolient for a week or two, and drop no of baths.
Its better to treat @ initial flare up, as will use less for less time. Also if leave will get itchy lo will scratch and the it can get infected.
DS lived in babygrows for roughly first year as otherwise he lifted his trousers and scratched legs till they bled.
I'm so glad its gone and that my 2 girls don't have it as bad.
Hope this helps and lo eczema settles soon.
Take Care
