There is no link but rather posters using common sense deductive reasoning. MOO
Why would the mother change her time line when she put the baby to bed earlier then what she first stated?
Neighbor goes over there, states to LE she never saw the child, nor DB never went inside to give the baby a bottle, change her, or kiss her goodnight the entire time she was there. Reasonable conclusion as to why DB had to change her timeline so DB can say the reason why was because she put her to bed before Neighbor came over. A BIG MOO but also based on common sense reasoning is all.
