I haven't had to travel. Kinda flatly refused to at the moment. But if I really had to I don't know how I would be able to do it. At the moment dd only goes to sleep from boob. Wakes up at night still for boobies. I totally understand the mummy guilt. Mine kicks in abt 4ish.
DS was the same until I went away (20 months) - I was a bit worried but he was fine, he didn't even ask for boobies but got right back into them when I got home, he stopped waking overnight for feeds after that trip :-) , but my mum was here I knew she could cope with him, but the three nights I was away he slept better than had ever done previously! I on the other hand did not sleep so well typical! !!
