Redness -nappy rash, allergy, teething?

For the last few days Blake has had red marks on his legs, like a ring but only on the front of his thighs and also has had redness and small spots on his lower tummy (where the top of the nappy sits) We're using ittis during the day and Foxybots at night and it really only happens during the day. I would normally think the leg marks would be caused by too tight elastic but they appear about 1-2cm below where the elastic is. I've tried doing them up looser but it still happens and he ends up leaking Anyone experience anything like this? It doesn't seem to bother him that I can tell but I'm sure it must be at least uncomfortable if not painful Is this nappy rash or heat rash or could it possibly be a reaction to something? Please tell me it's not my ittis cos I love them!

We use ecostore, always have. We've never really had nappy rash either, I didn't think it was because it's in an area that's not covered with nappy but I just didn't know what else it could be. The only other thing I can think of is that we've recently been using an exersaucer that a friend lent us so maybe that's causing the marks on his legs? I just hate to think that we may be doing something that's causing it

Does it bother him?

Jack gets random rashes quite similar but they never really bother him so I don't worry too much about it and they usually go away on their own.

Joel has spots like that on his tummy and gets a bit on his legs as well, I asked plunket last week and she said that it is most likely to be heat rash......which is what I thought it was. Doesn't bother Joel at all. He is also in ittis and it never occured to me that it could be them although I notice he has a red mark around his belly today so it maybe time to loosen then down to the next snap.
