bad mummy, bad bad

Yesterday I noticed the base of Oliver's thumb was red. Upon closer inspection, it is chapped, from being in his mouth half the day and most of the night. I put some vaseline on it last night and this morning. It's better but when I said something about it at school his teachers said they had been talking about it a while back and just assumed I noticed. UGH!!! I feel like the world's least observant mum. Makes me wonder what else I have missed. Once when he was a month or two old I was horrified to discover his belly button was cruddy. I was a wreck. So much for that being enough to scare me into being better.

To make things worse, it took Google to remind me that a little Lansinoh would be the best thing for this problem. Shoot me now.
