I visited the child health nurse at our local pharmacy, who I've been seeing since DD was 2 weeks old (and having her weighed there, so it's a consistent set of scales). Last time I saw her was 4 weeks ago, when DD was 13wks. In the past 4 weeks, DD has put on a total of 240gm, maybe grown 1cm longer, and head circumference is 1cm more. Between 10-13 weeks, she put on approx. 200gm/week, grew a few centimetres, can't remember head measurements for that time. I was sure she was growing more in the past few weeks, but it must be because I'm using bigger nappies that her clothes aren't fitting so well anymore!!
Breastfeeding has been a big struggle for us from the start, with horrid pain and nipple thrush until she was about 6 weeks old, extreme fussiness, I've comp fed on occasions (EBM or formula if no EBM) and used a supplementary line for a few weeks in December when her fussiness was crazy. I thought she was settling into a 4-hour routine in the past week and a half, she's not sleeping through (6 feeds a day), and is getting to be fairly fussy during feeds again (pulling on and off, not particularly happy when the feed's over - which is when my breast feels soft and she keeps on pulling off after one or two sucks). I'm going nuts and feeling guilty about her not gaining enough, and in my heart I don't believe she's a petite baby (3.58kg and 51cm at birth / 7lb14oz) who would only be gaining a small amount. She's now 17 weeks/4 months old, and not even 6kg!! I've been taking prescription medication as well as Blessed Thistle for the past two months to increase my milk supply. Even though she's been on a roughly 4-hour schedule, I still pretty much feed on demand, sometimes there are three hour gaps, and she's hungry, so I'll feed her.
In my head I know not to compare to other babies or trust what other mothers say, but someone saw her at the pharmacy today and thought she was a 4 week old, not a 4 month old!
I'm wondering whether formula might be a better option for her and/or starting on some solids in the very near future (as recommended by the paediatrician when she was 10-12 weeks old).
