I speak to Joshua's dad once or twice a year maybe, he never see's Joshua, never speaks to him or asks about him. joshua knows his dad, and wants nothing to do with. I keep communication open so that Joshua will never ever be able to blame me for him not having his dad around. Sometimes he gets upset and wants to talk about it, other times he says he prefers having a mummy who loves him than a mummy and daddy when he doesnt care. I just go with the flow. I answer what questions I can for him. He knows he has brothers and sisters with his dad, but they dont know Joshua is their brother although they have all met twice. I keep no secrets from Joshua, if he asked I answer truthfully (which will be fun when he eventually asks who is georges dad lol as right now he thinks the baby was in my tummy solely so he could be a brother lol) I did also keep in contact with his paternal family, it was always me making effort, and i regular email photos over, but since they had a new baby in the family they havent got back to me. I havent spoke to them in maybe 2 years now either.
OH is George's daddy and thats just how it is, not a word from the other, and I have no intention of chasing him, he knows where I am and I will talk if he makes the effort, same as Joshua's dad.
Both boys are identical to my brother except for their mouths, which are both paternal. The first picture of george in his Christening suit there is like looking at a baby version of his fathers son.
I would check for thrush if she has blisters hun, and thrush can be caused by teething, or just because it decided to flare up

Hope it clears quickly I would try a fungal cream under the barrier cream xxxx
