Love the set up in the first. Baby could have done with being propped up a little more to get the lower half of their face in the shot. Shallow depth of field is so often used with baby shots, but focus is critical and it's not on the eyes from what I can see (on a phone so could be wrong). 90% to being a great shot. Guessing F1.8 ? Try a little narrower.
Second one is good too. Unusual angle as you often just see the baby on the parent's arm without the parent in the shot. It's obviously posed but sort of looks natural, not that people tend to hold their baby like this, but I'm sure you know what I mean. Focus looks slighly of again? The background could do with some tidying up. If you have PS the dodge tool set to highlights at around 6% would clean up the edges and then increase the percentage on the plain areas to make it quicker to use. Doing this you will get a plain white for the background, rather than a creased white sheet draped over a sofa (or something).
Not bad for a landscape 'tog !!
