GYo, the only time I had any round bits in the middle was when he was transverse. Try not to worry too much about, if the baby has moved round, that shows there is still plenty of room for them to move back again, and IIRC, something like 95% of them do!
Tink, DH had the first 2 weeks off, the first week I was BF so he couldn't do the night feeds obviously, the second week happened to be when DS1 went back to school after the xmas hols, so I decided I was going to use the week as a practise run to make sure I could get all three kids up, ready, and out in the morning, even with broken sleep, so I did all the night feeds, as I am still doing. It may seem like he is getting away with it, but he works upwards of 12 hours a day, driving is a big part of his job, and when he isn't driving, he is messing around with water and electricity, so he needs his head in shape. We have switched to the ready made formula (expensive but worth it) so the first feed comes upstairs with us at bed time, if he needs another feed, DH comes down to do the bottle while I try and stop Mikey waking the other 2 up! If the second feed co-incides with us waking up, DH will sometimes do it if he's got time, depends where his jobs are that day, and how early he needs to be there etc. But, at the weekend (when DH is off, before last weekend, he'd been back at work for 3 weeks, and only had one day off!) he feeds him all night, and I get a lie in
