A good way to deter night waking (in babies over six months) is to offer them water in a cup instead of a milk feed.
If you offer water in a bottle, they may still be very happy to drink it, as they get comfort from the teat on the bottle.
They are likely to be really cross with you on the first night, and wake more frequently to test you, to see if you give in and give them a feed!
But if you persevere, they will quickly learn that there is nothing to wake up for, and then they will develop self soothing techniques.
If you are a shattered parent, keen to try this with your little one.... get in touch and I can talk you through it, it really works!!
