Hmm possibly although you need to consider a growth spurt too.
HV told me that he should have everything he needs in 20 minutes of feeding. I kinda follow this and take my little chap off after 20 mins and wind him. If he cries for more, i put him back on, for a "snack" type top up.
Nappies wet/dirty i presume? Are you getting him weighed regularly? i only ask as this is what reassured me that i was doing ok. keep going, you are doing a fantastic job chuck x
I didn't worry about it. after about 3-4 months I started putting her down a bit when she was asleep. and it was about 5 months before I could put her down before she fell asleep. from about 7 months she rarely slept on me any more I don't think there is a lot you can make them do before 6 months (I'm not an expert tho), but I do know milk and sleep is good!
It's fine, normal and healthy for your baby to use your breast for comfort if you don't mind this. Dummies are substitute mummies, not the other way round, as has been said. As your baby gets older you can use the breast to not only comfort your baby, but relieve pain too, due to teething, or immunisations etc. of course, again, if you want to do that. Breastfeeding is about so much more than just food.
Your baby will gradually grow out of comfort sucking so much and will also grow out of needing/wanting to feed to sleep, but you certainly aren't doing any harm by 'allowing' him to do these things, quite the opposite in fact.
