Feeding issues - help please
S is almost 23 weeks and ebf. I took him to be weighed this morning and he's only gained 1lb in 6 weeks. He's just dropped back to the 91st centile so I know there is no great worry that he's wasting away, plus he's starting to roll and therefore be a bit more active.
However, the HV was a little concerned with the small gain added to me explaining he's been waking more in the night for food (it used to be at 5 am, after 8-9 hours after milk, now it is mostly 3 hours, though sometimes still up to 7). He has also been faffing at the breast, crying as if he isn't getting enough and not seeming satisfied in the day even when I offer both breasts which I hadn't done for some time. This has only been for the past week, but does coincide with more feeds at night, which I didn't connect until this morning.
She seems to be querying supply issues, and told me to drink more fluids and come back in two weeks for him to be weighed, she also suggested block feeding.
I just wondered if anyone had any wisdom to share, about either supply issues, or about it possibly being something else? The other thing to mention is he's quite a sicky baby, so I'm wondering if he's getting less milk, and then being sick, is this making things worse? She didn't advise feeding more regularly than Sam asks because of his sickyness, as that was something that sparng to mind.
I feel really guilty as if I'd had him weighed sooner I would have known. I've been lucky that I've never had to worry about him gaining as he's always been really steady and has always fed well.
Any help appreciated, thanks.
