I currently use a nct close caboo with my 4.5 month old ds - he loves it and has all his daytime naps in it plus I carry him in it when out. However it is getting uncomfortable for me now he is getting bigger - he is 17 lbs - it also doesn't seem to be as supportive for him either. I think we will probably stop using it in the next month or so. Can anyone recommend a sling for us from 5/6 months plus - ideally one he could sleep in for naps? It has to be easy to put on too as I also have a 19 month old who demands as lot of my time! Thanks
