My daughter is 1 mo old today and in the last two weeks has started making a sucking noise with her tongue (I can feel it as well) She doesn't always do this. When she's gulping she won't make any noise except swallowing. Her latch seems to be good. No pain, gaining weight, plenty of wet diapers. However her poops arent' regular anymore. No poos for a day then an explosion. Any suggestions?
