Anne, some things I thought about after I closed my computer for the night regarding your question on a slow gain baby. I would want to know if these weights are with clothing or just a dry, fresh diaper (meaning disposable)? If these weights are with clothing, that would account for the oddness of the gains, why some weeks are high and some are low. Clothing throws the weight off or the baby weighs more one week with more clothing or a soaking wet diaper, etc. If baby has been weighed in clothing, then you must get a new weight with just a dry, fresh disposable diaper (cloth diapers may weigh too much) and start over. Now babies do not always gain steady but we like to see 6 ounces gain per week in the first 3-4 months. So, if baby was always weighed with just a fresh, dry diaper, I would recommend you look back at your listing and see what weeks baby was not gaining 6 ounces per week. The BAB says weight gain slows at month 3-4 so expect the weight to slow down about now. How many weeks does baby gain less than 6 ounces, and how many weeks does baby gain more than 6 ounces? Do you see good weight gain in the early days and now tapering off in the last 4-6 weeks, for example? Or the opposite? Also, count up the weeks of age baby is currently and take off 2 weeks (to account for the first two weeks when we expect baby to be back at birth weight). Count up those weeks and multiply by 6 ounces. Add that weight to the birth weight. What weight do you get? Compare to actuality. Example if 4 weeks old, we want to see a gain of at least12 ounces, that is 6 ounces times 2 weeks. Knowing how to calculate weight gain or loss is vital for any IBCLC. My other thought is that many 3 month old babies are sleeping longer at night. I would expect this to be fairly normal. I would also expect a 3 month old to still be nursing about 8 times (or maybe a bit more) per 24 hours. If baby is nursing less than 8 times, we often see poor weight gain and mom losing her supply. When baby sleeps all night, say 8 hours, then baby has to nurse more often in the day unless mom has a huge milk supply and baby has a huge tummy. I would expect a 3 month old baby to be removing about 3-4 ounces per nursing session, more or less. This amount times 8 is 24-32 ounces per 24 hour day. Some babies remove greater quantities of milk at each feeding, some mothers have smaller storage capacities, some greater, etc. A 3 month old that is truly nursing "all the time" meaning every hour all day long and waking several times in the night and who is not gaining weight properly needs assessment and intervention.
