My DS is 8months old and has had a dummy from about 4weeks. He has his dummy when he's tired in the daytime and when he goes to bed. He was sleeping through but has started waking for his dummy two or three times in the night. Other moms I've spoken too have said I need to wean him from the dummy as soon as possible otherwise it'll be really difficult further on. Is this wise? How do you do this? Help! Thanks in advance
