Who needs aerobic classes?

Every Tuesday afternoon Rosie takes me to her Baby Sensory class.

Apparently it's the best place to go to get to know people by poking them in the eye.  This seems to be the main method of greeting other small children, crawl towards them, push yourself into sitting position, reach out - and poke them in the eye.  They all seem to do it and hopefully it's something she will grow out of before she gets into trouble.

I am the only grandparent there.  All the rest are much, much younger than me (by about 30 years!) but are very friendly and welcoming.  Rosie is in the upper limit of the age group - it's aimed at 6 - 13 months old.  The younger ones who can't yet sit up are sitting targets for finger poking as they lay prone on the floor and I'm getting quite fast at crawling across the floor to retrieve Rosie before finger meets eye ball.  

It really is good exercise for everyone and I'm sure I use up as many calories as Rosie does.  Yesterday, however I think I was pushed to my limit.

"Today we are going to stimulate our babies' senses by swinging them through the air"

I looked at Rosie, and wondered a) how much she weighed and b) how much swinging was going to be involved.  Oh she loved it alright.  Picked her up, got her into a Superman position, swing to the right, swing to the left, now up in the sky, now down to the ground, right, left, up, down ...

"Wasn't that fun?  Shall we do it again?"

What?  Again?  I was just congratulating myself on surviving what was probably the most difficult work out I've done in years, and now she wants me to do it again?  Rosie's endorphins may have been flowing but poor nanny was feeling knackered.  Oldest adult there + chunkiest baby = I'm going to ache tomorrow.

It'll take me six days to recover just in time for the next session - wish me luck!
