Hello, I had DS3 earlier this year, he is now almost 6 months. I have found it pretty good going from 2 to 3 (certainly nothing like as bad as going from 1 to 2, and an absolute doddle compared with going from 0 to 1
).
DS1 was just 5 and DS2 v nearly 3 when DS3 arrived. No obvious sibling rivalry from either - have assumed that it's all old hat to DS1 (as he's been through it before with DS2, and it was quite rocky for a few months), and DS2 seems to adore DS3. I was expecting DS2 to be tricky as he is a complete mummy's boy and v physically possessive of me (still sticking his hand down my top at 3.5 - sigh), but he has not shown any aggression towards DS3 at all, thank goodness. He has been quite tricky in other ways, though - lots of tantrums, quite bolshy, not eating much, squabbling with DS1. But then, he is 3, so that could be enough explanation for all of that!
Both have been quite willing to help out, fetching nappies etc., which is nice.
DS1 and DS2 are v close, love playing together, share a room etc - they do squabble a lot, but are essentially v close, so I do worry that DS3 will be stuck on a limb, as there are just 2 years between DS1 and DS2, but 3 years between DS2 and DS3. But that will be a wait and see.
Am most daunted by the noise levels (2 are loud, so 3 will be deafening, I think!) and the amount they will eat as they get older
.
I must admit that some of this relatively positive experience of having a third is down to sheer luck, in that DS3 is an absolute honey of a baby, v sweet and smiley, incredibly laid-back. Wishing you the same!
