I keep reading about body pillows: snuggles and other assorted things with names that make me giggle. But then I looked them up and the price tag? It does not make me giggle. So, I have lots of questions: How necessary is something like this? Will it actually help me sleep through the night (other than the inevitable bathroom breaks)? How far along were you when you started using it? And, could I get the same (or similar) effect from a regular ($10) body pillow I could buy anywhere, rather than a specifically maternity one?
