I wouldn't worry about there being any kind of problem if his parents and pedi aren't concerned. Some babies are just more sensitive and need to be held more. My older daughter was a very fussy, high-needs baby. My younger daughter is much more mellow. It just depends on their disposition. And we are very much a "baby is always held" kind of family.
You mention that you care for your grandson - I'm guessing that means you do so on a regular basis? If so, what sorts of things do you need to get done? I'd recommend focusing as much attention on him as you can during the time you care for him and don't worry about things like chores or errands. And if there are things you need to do like making yourself something to eat, perhaps you could wear him in a sling or wrap while you're doing it?
Does he wet a lot of diapers per day and poop regularly? And has his weight gain been good? If so, you can probably worry a little less. As for "force feeding," that's pretty much impossible to do with an infant. You can't MAKE them eat. But if you're having problems with milk supply, I'd recommend you always nurse him first and THEN switch to a bottle. That should at least help maintain your supply. Good luck!!!View Thread
My LO isn't 3 month yet, but I've been lurking on your board.
My DH and I have co-slept with our 3-year-old and now with our new LO. Co-sleeping is a lot more common than you might think - but many co-sleeping parents choose not to advertise the fact that they do it. With our older DD, we never planned to co-sleep but ended up doing it because she slept so much better. Then we kept doing it because we loved it so much. She is now transitioning into a "big girl" toddler bed in our room, although that's been on hold a bit since DD 2 was born.
Here's a link to some great info on co-sleeping, including safety info:
