Our parents are helping to provide some of the needed bigger-ticket items since we're on a tight budget (terrible healthcare year for us last year, and now we need a car repair + a new water heater) and hadn't saved for a surprise. So I'm trying to figure out what to ask for. We cosleep/tandem the first 6-12 months, so we're going with a Pack & Play like we had success with last time. But I'm stymied on the car situation. DH is a SAHD and will continue for at least a while with this one. He is a BIG guy - like over 6' and over 300lb football player build big - so carriers have never been something he's comfortable with. Last time, we tried several slings, wraps, a Moby, an Ergo, a MeiTei ... nothing felt right to him, he just hand-toted our kiddos. So if it was ME staying home, I would go with a convertible carseat and slings. But with him being the primary at-home toter of kiddos, which will include shuttling the two bigger girls this time around & probably more vehicle time than before, I'm thinking we might still need to do an infant carrier + a later convertible. I just hate to spend money on two systems when one could technically do. Thoughts?
With our first we transitioned from the bucket seat to the convertible pretty early as the combination of seat plus baby got heavy for me. With our second, I delayed the transition as long as I could. I liked being able to have her contained in the seat while I helped our older child with 2 hands. Since weight won't be an issue for your husband, I think it would really help him to have the bucket seat. He can set it down and know the baby is safely contained while he handles the older children. They make higher height and weight bucket seats. Most women find them too heavy, but they may be a good fit for you. Our second didn't max out the height on ours until a little after a year and she was 97th percentile for height. The weight limit for us is a joke, our oldest daughter didn't reach the weight limit for the bucket until she was 27 months, I think it was. With boys, it might be different, but I doubt it would be a lot different.
ETA: I should also add, that you can turn the bucket seat in for a discount on the next seat at some places, so the extra cost can be minimized.
Anyway, then I walked into Target last week and they had a Graco Travel System (bucket seat and stroller) AND a Britax Marathon convertible seat both on clearance (discontinued fabric patterns) so we bought BOTH for less than the original cost of the travel system. Lucky me!
Anyway, I think we would have ultimately ended up with both anyway.
