I'm with Shawn, very nice work. there's no obvious bad compositions or anything. Nice wide range of lighting and poses. The one where you thought there might be a color cast looks good on my mac laptop.
They're all fantastic. My favorites are 5,12,15 & 23. So if you get rid of any, don't get rid of those! Some of them look pretty blown out FROM FAR AWAY but once you actually view the photo they look perfectly beautiful :)
BTW, I really like 5, 9, 12 & 15. 9 and 12 in particular would make me want to hire you to take photos of my kids if I had any :-). I love the contrast in the B&W portraits; people feel compelled to really flatten out portraits and often that is a good thing, but as you've shown you shouldn't make it a rule.
In my opinion, I would scrap images like 7, 8 and 10 -- they're nice photos, but are nowhere near as strong and compelling ways to photograph an infant as images like 5 and 11. In my opinion, the first page (00 - 18) are much stronger than the second page. I find 19 through 23 to be especially uninteresting. 21 looks like a mug shot to me. Portraits like 27 and 28 are well done, not super interesting, but a required part of a strong portrait portfolio.
I think your biggest strength is the remarkably intimate family portraits that you have, like number 11.
