Thank you Katy & Sara. Here are the answers to your questions (I haven't answered these before).
He is solely breastfed (every 4 hrs). He has never been willing to take a bottle. He has always breastfed for on average 6 minutes. He typically will not switch sides. He is putting on weight, so my doctor has said he must just be an efficient eater. Perhaps of relevance, they did say that his stomach was measuring small when I was pregnant with him (but, there have been no concerns of this since he was born).
He has two teeth (he got these both in his 5th month). He is 6 mos and 1 week old. I have given him pain meds in case this is teething, but it doesn't seem to help really.
He is having solids. Rice or oatmeal cereal two to three times a day. He has also had sweet potatoes, butternut and acorn squash, green beans, applesauce, and bananas. I make his baby food, but I add nothing but the vegetable and perhaps a little of the cooking liquid per a recipe book I have for making baby food. We do make his cereal with formula (it has been too much of a challenge to pump with two little ones, since he doesn't take a bottle at all). I know this seems strange, but since we have added a third meal a day, it seems worse. (A reaction to the formula?). Also, on the chance this could be useful: I know they say that you shouldn't worry about constipation in breastfed babies, but his stool has become very thick and he strains to get it out. On, the other hand, I could set a clock by his bm (he is very regular and predictable).
He takes Zantac (.7 ml/3 times a day). He loves to sit up right (versus tummy or back). He has been making more effort to crawl of late (i.e., getting on his knees a little) and scooting around, but he does not seem to be trying to crawl at night. I remember when my daughter was learning to crawl, it was as if she was practicing crawling at night, not so with him. Also, when he wakes, he is often crying and takes awhile to soothe.
Other potentially useful information:
He has been a very easy baby in a lot of regards. Doesn't cry a lot. Very sweet, smiles and giggles a lot and easily. He does seem to cry more at night with the wakings. He seems to arch his back when we are holding him upright. I am sticking with the bw methods (i.e., not using mobility props to soothe). This seems to be worse of late - strangely as he is eating more solids. Thank you so much. Jennifer
