Feeding Baby Rabbits: Alfalfa, Weaning, and Healthy Growth
Baby rabbits have very different needs from adults: they run on their mother's milk, then protein-rich alfalfa hay and pellets to fuel fast growth. This overview covers weaning ages, what to feed at each stage, when to introduce greens, and the crucial switch to grass hay as an adult.
Quick answer
Until about 3-4 weeks a baby rabbit lives on its mother's milk, then gradually starts nibbling alfalfa hay and pellets, and is usually weaned by around 6-8 weeks. Young growing rabbits get unlimited alfalfa hay and pellets for the extra protein and calcium. Around 6-7 months you switch them to grass hay and limited pellets for life. Never feed alfalfa as a staple to an adult.

Newborn to weaning
Baby rabbits (kits) are born blind and hairless and depend entirely on their mother's milk. A doe usually nurses only once or twice a day, often at night, so you may rarely see it — this is normal and doesn't mean she's neglecting them. Do not try to bottle-feed healthy kits with a mother present. Around 3 weeks their eyes are open and they begin sampling their mother's food. If you have taken on an orphaned kit, that is a specialist situation — contact a rabbit-savvy vet or an experienced rescue rather than improvising, as cow's milk and many formulas are dangerous.
Babies get protein-rich alfalfa; adults switch to grass hay like timothy.
Why alfalfa for babies
Alfalfa is a legume hay, not a grass hay, so it is much higher in protein, calcium and calories than timothy or other grass hays. That richness is exactly what a fast-growing baby needs to build bone and muscle, but it is too much for a fully grown rabbit and can contribute to obesity and bladder sludge in adults. So alfalfa is a growth food with a clear expiry date.
Feeding from weaning to 6 months
Once weaned, a young rabbit should have grass and alfalfa hay available at all times plus a good junior rabbit pellet, which you can offer fairly freely at this age to support growth. Fresh clean water should always be available. Do not rush vegetables: a young rabbit's gut is delicate, and piling on greens too early is a common cause of diarrhoea, which can be life-threatening in a baby. Keep pellets and hay the foundation for now.
Under about 6 months, alfalfa and pellets can be free-fed to support growth.
Introducing greens and the adult switch
From around 12 weeks you can begin adding leafy greens, one new type at a time in tiny amounts, watching the droppings after each (see our guide on introducing greens). Then, at about 6-7 months as growth finishes, make the key transition: gradually mix grass hay (timothy, orchard, meadow) in with the alfalfa over a couple of weeks until alfalfa is phased out, and cut pellets back to a small measured daily amount. From here your rabbit eats an adult diet — mostly grass hay — for the rest of its life.
Quick FAQs
When can baby rabbits eat solid food? They start nibbling hay and pellets from around 3 weeks and are usually weaned by 6-8 weeks. Until then their mother's milk is essential.
Why do baby rabbits need alfalfa? Alfalfa is high in protein and calcium, which fuels rapid bone and muscle growth. Adults don't need that richness and shouldn't have alfalfa as a staple.
When should I switch to grass hay? At about 6-7 months, once growth finishes. Transition gradually over a couple of weeks and also cut pellets to a small measured amount.
Can I give my baby rabbit vegetables? Only from around 12 weeks, introduced one at a time in tiny amounts. Too many greens too soon commonly causes dangerous diarrhoea in young rabbits.
