Hi, I've read previous posts about using dummies but wanted to find out how early everyone started using dummies if at all. I'm feeling a bit of a failure as i can get my baby to sleep in my arms after a good feed but he often wakes up when i put him down. Using a dummy puts him to sleep. And so far he spits it out when in deeper sleep. He's only two weeks and i keep reading that he shouldn't have one until 4 weeks to ensure that BF is established.
