Cusco & the Sacred Valley is at its best for hiking in May to August. Good but not prime in April and September.

No reliable monthly crowd data for this destination — the proxy used elsewhere did not pass its checks here, so nothing is shown rather than a guess.
Swipe the table sideways for the rest of the year.
The Inca Trail closes for the whole of February every year for maintenance and reopens on 1 March. Machu Picchu itself stays open and is reachable by train — so February is a fine month to see the ruins and an impossible one to walk to them
The Inca Trail must be guided by law; most other routes need neither guide nor permit. Acclimatise two or three nights in Cusco first.
February for trekking. The Inca Trail itself shuts for maintenance and it is the wettest month — but the walk still works: Salkantay, Lares, Choquequirao and Ausangate stay open, and Machu Picchu is open year-round by train.

Cusco sits at about 3,400m, and children are as susceptible to altitude as adults — they just describe it less clearly. Most itineraries that start high should start in the Sacred Valley instead, which is a thousand metres lower.
Sleeping in the Sacred Valley rather than Cusco for the first night or two is the single best altitude decision available. Ollantaytambo also puts you on the train line.

Kept out of the score on purpose. Averaging a rare catastrophe into a monthly number would tell you something false; the warning is the honest form.
Permits are the whole planning problem here. Only licensed operators can issue them, independent walking is not allowed, and March departures sell out first because everyone displaced from February moves there.
