1. It is not 'normal' to carry a child for any distance in the way Tanner's sighting was allegedly carrying the child.
2. On as cold a night as we are lead to believe it was ( Tanner had a large fleece on we are told ) no it would not be normal behaviour for not one but two unconnected fathers not to put warm apparel on their child's feet be that socks, slippers or shoes.
3. Tanner did not see a covering so I would assume if SY are tying the two together Crecheman's child wouldn't be covered either.
Your final assertion does not take into account my points made above.
Re: point 1 - can you please tell me why it is not normal? Is there a prescribed way of carrying a sleeping child recently scooped out of bed? Do we know that Tannerman carried the child the entire way in that manner? If Tannerman is indeed Smithman then evidence would tend to suggest he moved the child into a more accommodating position for himself to carry.
Point 2 - that's a matter of opinion. I would venture that a father would rather not wake a sleeping child to put shoes and socks on its feet, especially not as the child is not walking anywhere. If you can provide some empirical evidence that all fathers would cover their sleeping children's feet when moving them from one locale to the other then I will concede that point.
Point 3 - Jane does not categorically state no covering does she? And even if she did, would this be a deal-breaker in terms of tying in the two sightings? If most other points concur then blanket or no blanket could be explained by the fact that it was dark and she only really got a clear view of the child's feet, which in theory called have fallen out of a blanket.
