Looking for some advice, DS (PFB) is 8 weeks old tomorrow, he has his 6-8week check with the GP and I will be asking them too but wanted to hear your thoughts:
Short story: He's still gaining weight, but not as much as expected, droping from approx 15th to 9th centile in two weeks. I was expecting as much and took him in to be weighed today (HV said could wait 4 weeks) because in last two weeks has reduced how much formula he will take - was on 3-4oz 7 times per day now on 2-3oz 7 times per day. Also quite constipated with last few bowel movements being firmer than normal. Weeing fine, no vomiting. Has had a recurrent/long running cold (blocked up) but otherwise fine and happy in himself.
Longer/back story in case its relevant: DS was initially EBF but lost 12.5% weight by day 3 and was admitted back to hospital for 2 days and put on formula top-ups. Discovered I wasnt producing enough milk, stopped being able to latch him on after about 2 weeks. Continued expressing as much as possible (tiny bit) until 5 weeks and then gave up for own sanity. So EFF since 5 weeks.
Told HV at weigh in clinic my concerns today, told as he is still gaining not to panic but as dropping centiles come back in two weeks to check. Also suggested trying next teat size up, now he's already on the 3+ month size (has been since 4 weeks as helped with wind and slow feeding) but I will try him on the 6+ month ones i guess.
Finally(!) spoke to doc today as concerned about constipation: previously only pooed every two days but was soft and normal so not worried, last couple of weeks seems to be getting firmer and last week has been distinctly firm poo (the first bit, then loosens out - sorry if tmi) and going 3-4 days and in discomfort. Doc suggested adding water to feeds and using colief. Am concerned that adding water to feeds will mean he eats less overall and therefore exasperate above problem.
That was long, sorry [hblush]
