Maggie, they say 3 times and it's a habit. One night waking doesn't mean it's a pattern so it could still go either way. I dream feed Tom at about 10pm but he nearly always still wakes for a feed around 3 or 3:30. I know he's hungry so I feed him and he guzzles. He has only gone 3 nights without waking for a feed.

Personally I don't think you've done the wrong thing feeding him, but that's just me. Jack started sleeping through the night at 6 weeks, but occassionally would wake in the night. I would feed him and he would still sleep through the next night so I don't think it formed a habit. But I know that other people have other experiences so this is just my opinion.

Teething could well have been the reason your DS woke, especially if you're sure he wasn't hungry. Tom is just on 5 months and got his first 2 teeth this morning. You will find night wakings will occur with teething and developmental milestones. You will have to decide whether you comfort feed at these times. Some people do and other don't. I'm in the do camp. I find if it settles them back to sleep, it's better than them crying or being distressed. And once they cry a lot it wakes them up and then they are less likely to go back down. So I pre-empt that and feed straight away. I know this isn't what you have been told, and it's not for everyone. It's a personal thing. It really comes down to what suits you and DH. I am sure there is a risk of a habit forming if you do comfort feed so you have to weigh that up. Good luck, I hope you find what works for you.
