I'm trying not to obsess about this, really I am. But I looked up average weight gain charts for infants and compared them to how Donovan has done these past 7 months. I looked up average weight gain rates on kellymom.com and compared them to Donovan's, and the results are below:
Donovan's growth rates:
1st and 2nd month: 220 grams/week (average is 150-240 g/wk)
3rd month: 155 g/wk (avg is 150-240 g/wk)
4th month: 143 g/wk (avg is 150-240 g/wk)
5th month: 80 g/wk (avg is 90-125 g/wk)
6th month: 62 g/wk (avg is 90-125 g/wk)
7th month: 42 g/wk (avg is 50-80 g/wk)
Looking at these numbers was sobering. I'm realizing at the moment that it's still hard to tell, as the Kellymom chart is ambiguous (for example 4 months is listed in 2 different brackets it's unclear whether the average weight gain for a 4 month old is 150-240g or 90-125, which changes things-- though even then he'd still be under on his gains for his 5th and 7th months).
This is unfortunately the exact sort of problem I gave the hardest time with. What needs to be done here is to decide on a course of action, watch D's input and output, and re-evaluate things in one month when we've weighed him again. But instead I question and second-guess constantly, frustrated by the utter lack of any feedback to let me know if what we are doing might be working or not (and this is the state I'm in just 2 days into it).
The worst part is just not knowing how big a deal to make of all this. Looking at his weight gain, I'm guessing this isn't just a one-time random dip but part of a pattern, and that while achieving mobility or starting solids may be part of the problem, neither is the entire story as his weight gains started slowing as early as 4 months. Now, is this just his own individual growth pattern, perfectly normal for him? That wouldn't surprise me, seeing how much regard D seems to have for "average" and "normal" ways of doing things, and Zach has reminded me more than once that he himself was fretted over at about 8 or 9 months of age for being too skinny of a baby and it was no big deal. Or is this slowdown going to continue and will it become more serious over time? There is no real way to tell other than to see what happens.
I'm trying to do what I can to get him to eat more, while also looking at his overall happy demeanor and wet diapers and deciding that clearly he's not a kid who's suffering. Most likely this is not a big problem. Hell, even if it is I'm not sure how much more we can do about it at the moment. So I'm trying not to freak out, take things one day at a time, and just see how things play out. We'll see how successful I am at this.
