My DS used to religiously follow the 2nd centile (after some early supply probs with supplementing in the early days, then me pumping like a mad woman, taking domperidone etc). HV said she was happy with this as he was clearly healthy, developing ok and gaining along his own line. He is a v active little boy (commando crawled at 5.5mo) so I just supposed he was burning off the calories.
Then! we started BLW at 6mo. And he just eats and eats and eats - so much so that he's been gaining 9oz/week since we started solids, so he's now halfway to 25th centile and has got noticeably fatter, and heavier to pick up, in the last few weeks. He is BFing less - still wakes at night but not swallowing as much as before and often only wants 1 side (used to be 2+!). At night he now often makes his latch so shallow that he is just "comfort sucking", which is making my nipples sore again for the first time since the very early weeks. Am trying to offer BF as often as I remember, but he just does not ask for it like he used to and his feeds are v short. I know they are supposed to self regulate how much they eat, but he doesn't seem to do this. If he likes the food, he'll keep eating until it's all gone. In contrast he takes hardly any water from his cup - if he's thirsty, he'll just BF.
I guess I am not that bothered if he's getting a bit too much food in the short term, as he is healthy and happy and still similar to or slightly slimmer than most babies we know in RL (mostly FF though) - but what I am bothered about is if he is cutting down his BF too much - surely his solid food won't give him the nutritional and immunological benefits that BF will.
Should I restrict his solids to make sure he takes enough BF? Or should I just trust him to eat and drink as much as he likes?
Complicating factor: am going back to work in a few weeks' time so this may all change...
