“Dame Tilbury’s daughter has lain-in—Shall I give her any of your Baby clothes?”

In the index (Letters) is says there are two families of villagers of this name. I think I read somewhere they would give clothes away to servants? In Letter 1, they trimmed up and gave away all of the old paper hats and she hopes CEA won’t regret the loss of hers. (?) So is she asking permission to give clothes away? If so, are these clothes CEA made, it would seem a long time to keep her own actual baby clothes—or is this just a joke?
