Since LO's birth we have used a bassinet in our Quinny stroller. At 5 months, she is getting too long for it and is almost at the 15lb weight limit. We don't have a car seat attachment so the next step is to use the Quinny seat. Is a stroller seat safe to use at 5 months? It does recline, but not fully flat. She has good head control but does not sit up yet. Even assisted she's pretty wobbly. When did you put your LO in a stroller (without a bassinet or car seat)?
