My LB is 7 months. I've been working one day a week since he was 6 weeks old when DH has had him, now I'm back a second day with DM and DMIL taking it in turns. DM had him yesterday and instead of sleeping through from 7 til 4/5 he was up 3 times in the night. He's just taken 30 mins to go off in his cot instead of usual 5 mins. I know both mums have let him fall asleep on them which I've tried to stop him doing. Do I need to speak to them or could it just be teething? I don't want to upset them as he loves his days with them and it helps us out a lot.
