My DD just turned 5 months, we try and do feed play sleep but as some days we have alot of trouble settling her for day sleeps it can gp out of the window. I would like to have more of a routine going but I just go with the flow.

We usually bath her in the middle of the day, our bedtime routine is:
Feed on one side, top and tail sponge, massage then feed on the other side, into bed with CD and soft toy. Most nights this works well. We also give a dreamfeed.

I know there are lot of books around with suggested routines that you could borrow from a library but all the ones i have read my DD will definately not fit into and I don't want to force her into a routine.
What someone suggested to me once was to chart for a week the times your son feeds and sleeps and you may see a pattern emerge that he is roughly going down for naps around a similar time so you could structure a routine around that.
