Thanks for all of your comments, sorry not been logged in for a while, as after the farrier visit we went ahead and bought him. Farrier agreed that his toes were a little long after not being trimmed for a long while, but there is no sign of laminitis. We have since had him out in walk and trot and is doing brillinat, In fact he has such a beautilful gentle little trot and shows no sign of lameness at all. His response to voice commands is second to none!
I read that one poster, posted about the children out growing him quickly. In response to that, he stands at 42 inches, and will last my daughter for the next 6 yrs at least as she in only 2. I bought him for the purpose that they can grow together. I would never be ale to get rid of him or pass him on, I view him now as a family member, and worse case scenario we will part loan him to another little person looking to ride. His is such a little love on the road and with the kids I would never see him go to waste. On the same hand, he will always be in our family if it be ridden or companion. Its the best decision I ever made, as he has made our family complete.
Thank you once again for your comments and advice, it allowed me to take the right steps to have him checked, and hopefully we now have a pony that will make my children (and me) very happy xx
