my 2 week old is falling asleep on me but wakes up 10mins after being put down, whereas if I don't move for a few hours he sleeps fine! He does sometimes settle but seems to prefer sleeping on me. I was thinking of getting a sling so I can at least carry on with other things while he's attached to me. Am wary if buying one without asking first as I'm a size 20 atm so worried it'll arrive and not fit me! Any recomendations?
