She had one spot on Thursday woke up with more yesterday and now today they're really itching her. She's 17 months old and I don't think I can give her antihistamines until she's over 2. Any advice? Got virasoothe that I used for 3 year old and it only helps her for a couple of minutes. Shes literally rolling around the floor crying constantly because they're itching her so much. I have had to put her in her cot for a little while so I can make her sisters breakfast etc because she is clinging to me constantly. I feel so bad for her. Any suggestions?
