2 of mine have had a dummy. DD1 til 6 months & DS til 4 months. DD2 was a reflux & colic nightmare & refused it from day one.
DD3 has started showing signs of reflux, so I've just started her on one. Tonight is the first time she's gone to sleep with it, coz the second I took my boob out of her mouth she was awake & screaming. So far I've put her down & she's been there about 20 minutes... shhh.......
