DS is 4 months old. Sucking his fist has developed into sucking his thumb occasionally. Not all the time, maybe once or twice a day. Whether it makes it in by accident or intention, I'm not sure.
Personally, me and DH are not fussed. We think he'll grow out of it. He's hardly going to go to his first job sucking his thumb!
However, MIL and SIL are acting like he has developed a heroin addiction. It's been suggested that we give him a dummy instead. Even DM has said it's easier to take away a dummy rather than a thumb.
I haven't given him a dummy so far and don't really want to. It took a long time to get him latching on well and still sometimes ends up with a shallow latch and has to be taken off and put back on, so I don't really want to introduce a dummy in case it hinders the breastfeeding.
AIBU in my attitude to said thumb sucking?
