I just found out that BOTH of my twin boys (5 months) need helmets :o( Does anyone have experience with helmets that they could share? Do the helmets hinder their development at all? I'm worried about them not hitting milestones because they're lugging around a big helmet. Were your babies bothered by them? Any tips or tricks you can share about making them comfortable. How long did your baby have to wear it? Obviously it's not an ideal situation but I know it's temporary and will definitely help them in the long run. Thanks!
