Harriet, sorry to hear you are feeling down. You take special care of yourself. Thinking of you.
Tribble, hope your LO is better soon. How annoying re spilled food.
Flowers, well, my gym is local, so not too much of an effort to get to - I walk with DS in a sling, as I don't like leaving my pram unattended. I have a small wheely suitcase with all his kit in (swim nappy PLUS swim snug PLUS neoprene outfit - for containment AND warmth!) and the inflatable ring (which I leave inflated). He actually puts his legs out for slipping through the legholes now! So I get him changed quite quickly, I already have my costume on. I have him in the inflatable ring when I get in the pool. Getting out is not the easiest, as there are no graded steps, just a vertical ladder, but I manage. I did go swimming alone at the hotel in Liverpool when we went to that engagement party a month ago and getting out of that pool was really difficult.
DS loves swimming, we do 45 minutes, I sing nursery rhymes to him, like If You're Happy And You Know It (Splash Your Feet!), or Five Little Ducks. Take him out of the ring after 20 minutes and swim lengths without it, sometimes on his back, and he kicks. Sometimes I dunk him, but not every time. After this he is famished, so I quickly shower him, get him out of his costume, nappy on, and BF. This often zonks him out, so I put him in the suitcase asleep while I get changed! :) I have a lovely photo of him like this, I might see about uploading it to my profile! :)
Er, not sure if I have helped at all - anything specific, please feel free to ask me.
