Erm. DH got annoyed with his MiL for taking Liebs swimming before DS did. DH had PLENTY of opportunities to take DS swimming, just that fishing/playing at building a car/PS3 were more important. DS was over 2 years old when Mum took him swimming. OK so DH maybe only had 20 missed opportunities, but if you want a first, you grab it first. I brushed Liebling's teeth as soon as one appeared. How long has your child had teeth?

I'm not defending your MiL, she should let you be the parents. But if you're missing opportunities, can you grab them first? I know with my mum you have to jump in first and if you aren't ready argue til you're blue in the face then not leave her alone with Liebs, but some of it is just DH not stepping up and being upset when someone else does.
