My son is 2.5 months old and he always seems to have lint/fluff between is fingers and toes…he gets a bath every night but regardless whenever I look there’s white/greyish fluff hidden in there. I can see the toes getting it from his socks but where is the finger fluff coming from…and while I’m on this topic, why does he seem to be hiding treasures between his neck rolls that are next to impossible to keep clean ? Anyone else have this with their babies.
Re: What the fluff ?
My sister used to have that. I didn’t like her and I remember biting her fingers one day when I was 2. (She was a wee baby at the time). Got a mouthful of fluff 
I don’t remember biting her again afterwards.
Anyways, so I think it’s not that uncommon for babies to have lint between their fingers and toes. I think it might be coming from socks and gloves that the baby wears?
Re: What the fluff ?
My son is also 2.5 months old MA. And yeah he has the same thing in between his fingers, his neck and everywhere else where he has a roll of fat. lol.. I clean it everyday. Even when I give him a bath I still see it so i just kinda clean it. I think the reason is because babies have their palms closed, that fluff thing gets in between the fingers and palm (in the lines if you notice) and gets stuck there.
I clean my baby's neck after each feed. Milk+dust makes a weird thing and it just gets stuck there. I have to clean it. And my lil guy also has doule chin.. so its hard to clean, he hates it! I knew from day one about this as my mom told me to clean these parts everyday. I am thinking all babies have this issue.
