It makes sense defensively to change the timeline.
If time of death is around 1030 - when she last claims to have seen Lisa - she hangs herself. If she changes it to 6:30-6:40 then she can say well, it wasn't me, the last time I saw her was 6:30.
If DB is responsible, she KNOWS the TOD for LI. It would be stupid to claim that the last time she saw the baby was the TOD. Adding the drunk factor, lends the credibility (in her mind) to sleeping through a break in, and for messing up the timeline initially. A blackout would take you from pre-meditated murder (1) to man slaughter.
While completely transparent, it was actually probably the smartest thing she has done.
