Hello
We buy fab pjs from www.eczemaclothing.com - Cotton Comfort. We have just had their latest catalogue in the post (I find this better than the website). Here is some info re socks and tights but you need to see the catalogue really or phone the excellent helpline (01772 331815 - Mon to Fri 10 - 4 pm - you may get diverted to the sales line if they are busy so I suggest ringing back later as the helpline staff are very knowledgeable).
Children's socks
Knee Socks - flat, hand linked toe seams are mentioned £15 for 3 pairs - grey, white, red, navy - all sorts of sizes; 100% cotton from controlled biological cultivation; code C41
Ankle socks - as above incl info re seams but more colours - sea green, bottle green, natural, plum, raspberry, loganberry, denim mix, royal; £12 for 3 pairs Code 33
Children Tights
Flat knit tights - looks seamless on the photo but not sure - navy, white, pale pink, pale blue £8; code C38
Soft Ribbed tights - flat hand linked toe seam - raspberry, grey, natural, bottle, plum, royal, cherry, navy - £8 - £12 Code C28
Yes rather pricey but you get what you pay for with this firm. The pjs are seamless. The labels are sewn on the outside and can be cut off.
Alternative ideas - what about foot massages to help them get used to touch? Are they sensitive to touch eg hair brushing/combing, towels, paint and anything wet? This can be a clue that someone has dyspraxia or sensory processing disorders (needing sensory integration to help adjust to this). My children are hypermobile and have sensory processing issues, as above, plus dislike of loud sounds etc. Occupational Therapy ideas have really helped. Gone way off topic here but thought I should add this in case it is useful.
Good luck with the school run and dressing! Oh yes, would a mirror help beside them to help them adjust the tights etc?
