I am new to this idea but I am very interested. I have a 4yr old, 3 month old, and one on the way I am thinking that baby wearing is going to make my life a lot easier and just had some questions if you all don't mind sharing your opinions.
What is the safest/most comforable one to buy for a newborn that makes breastfeeding easy or is that safe/possible?
Should I introduce my 3 month old son to it or will that cause issues when the new baby comes along?
Also I was put on bedrest with my son and I am imagining I will be with this one also since the pregnancies are so close together. Is there a certain type that would be considered safe if I was to get any lifting restrictions?
1) There are TONS of good proper carriers that are very comfortable to use with newborns. The type of carrier I recommend most for newborns when wanting to breastfeed in a carrier is ring slings. There are many reputable brands (Sakua Bloom, Maya, Zolo, Taylor, etc) but I recommend Sleeping Baby Productions just because she's fantastic to work with and her prices are very reasonable (do note her shop is currently closed due to school starting for her kiddos but she'll be open again soon). While not everyone finds BFing in a carrier easy, there are more success stories with ring slings than other carriers. The only carrier I felt that I mastered for BFing was ring slings though it wasn't till DS was a few months ago. But I didn't really try very hard back then since I didn't have other little kids to motive me. Another carrier type that can work with newborns (and is an excellent bigger baby and toddler carrier) is mei tais. Not as easy to BF in, but I managed it so it is possible! Many women do report that they weren't able to BF hands free in a carrier, but one handed was better than nothing. I have managed to BF hands free with ring slings and mei tais (though not till DS was 6 months).
2) You can definitely wear your LO! I'm currently 27.5 weeks pregnant and wear my 26lb toddler all the time. I will say that as my stomach has gotten bigger I've had to rule out front carries and only do back carries (he's too tall to sit above my belly lol). I actually plan to tandem wear (so wear them both) when necessary (like grocery shopping cause my son climbs out of carts easily). Otherwise I'll wear one and push one in a stroller (I'm honestly wondering if it'll be easier to wear the active escape artist toddler and stroll the baby ha ha). Some women find SSCs (buckle carriers like the Ergo) to be fine for back carries when pregnant, but I personally find it uncomfortable and have stuck mostly to back wrapping with a woven (do note it is a high learning curve but totally worth it) or a back carry with a mei tai (like Mei Tai Baby, FreeHand, Kozy, Beanslings, etc). I've used a ring sling some with hip carries, but DS prefers back carries - just his personal preference.
3) It depends on your restrictions but I do find that I can baby wear my toddler much longer than hold him - even before pregnancy! Being up against me means that he's not working against my center of gravity and I have my hands free for hold on to my stair rails and such. Some women do fine with BWing with lifting restrictions, where others don't. Something to talk to your care provider about (and if s/he isn't familiar with BWing, showing often helps them figure out if it's appropriate for you or not). Any carrier when used properly will keep baby safe against you hands free.
