With the peas' I give them processed peas which are softer and easier to shell...... The cucumber I do 2 ways... Let some float as they like to chase it around and catch it.... (Sliced thinly)
The other ways is sliced quite thinly but held down with a fork till they eat it.....
Regarding growth mine were fairly small for a while then took a little growth spurt but it seems to me the more they eat the quicker they grow....(I know some might think that obvious)..... Not saying starve them just incase anyone is worried... wouldn't do that but just dont overfeed ......
