Skull Woods
Baby #66
There are two southern entrances to Lost Woods proper. Take the eastern one; there's a large boulder blocking the path. Lift it to discover a baby underneath.
Baby #67
Look south between the two entrances to spot this one attached to a wall.
Baby #68
Now head up the western path and enter the woods proper. Follow the path to reach these two puffs of grass. Slice up them up to discover another baby.
Baby #69
Now head to the northwest corner of the woods. Here you'll find a skull surrounded by grass; there's a baby inside this strange arrangement.
Baby #70
Head to the destroyed house just east of the woods (the equivalent of Rosso's house in Hyrule). Look south and use a Pegasus Boots charge into the tree here; you'll shake loose a baby.
Baby #71
Head south to find these trees arranged into a V-pattern. Slice up the purple flowers in the middle to reveal another baby.
Baby #72
There's another baby in this direction, just a bit further south. Enter the pit to find it attached to a wall.
Baby #73
Now move west. Just beyond the gateway for Thieves' Town, you can see this baby attached to a cliff wall.
Graveyard
Baby #74
There's a large boulder just outside of the Lorule Sanctuary. Underneath is a baby.
Baby #75
The next baby is attached to the wall north of the Graveyard proper.
Baby #76
Follow this region until it wraps southeast. Use a Pegasus Boots charge on the tree here to shake loose a baby.
Death Mountain
Baby #77
As you ascend, stop at this ledge and drop down. Bust up the skull to free a baby.
Baby #78
Take a left from the Treacherous Tower. Use the Hammer to clear the pegs, then move to the western edge of the platform. Lift the boulder here to reveal a baby.
Baby #79
Head to the incomplete bridge just south of Treacherous Tower. Lift the boulders here to reveal another baby.
Baby #80
This baby is found in the exact same place as Baby #26, just transposed to Lorule. Break up the skull on this ledge to find it.
Baby #81
This is found high on a cliff wall in the extreme southeast corner of the mountain. Merge from the higher ledges to the north to reach it.
Baby #82
The last baby here is just "chilling" on a rock face behind the Ice Ruins.
